## Overview

The program sends commands to the CD-ROM controller and polls for each interrupt. Each line of output gives the interrupt type and the response bytes, and the number after @ is the time in cycles of root counter 2 from the command write. A mark such as "..(2)" shows a response of two bytes of which only the first is printed.[^o] The first group runs with the lid open and no disc. The program then asks for the Twisted Metal 2 disc on the screen and waits for the lid to close, and every later group runs with that disc in the drive.[^o]

The disc holds 12 tracks. GetTN answers 01h and 12h, and GetTD 00h gives the lead-out at 69:22, which the program counts as sector 312000.[^o] The program ran three times with different groups. The second and third runs also send commands 50h to 56h after GetID. The first run prints no such step.[^o][^p][^q]

Table: Groups

## Results

### Test Refusals With No Disc

With the lid open and no disc, every Test subfunction in the list was refused with INT5 and stat 11h. A single parameter gave error byte 10h, except subfunctions 50h and 71h, which gave 20h. Every row with a second parameter byte of 00h gave 20h, and so did 74h 00h and 71h 00h 00h. The answer came 23,418 to 37,986 cycles after the command.[^o] The [CD-ROM commands](/hardware/cd-rom/commands/) page lists the stat bits and the error bytes that the drive returns with INT5.

### Disc In and the Table of Contents

In all three runs GetID answered INT5 with error 80h for 14 to 20 tries. It then answered INT3 42h and INT5 4Ah 90h 20h 00h 00h 00h 00h 00h.[^o][^p][^q] Commands 50h to 56h each answered INT5 43h 40h.[^p][^q] In the third run MotorOn, sent every 50 tenths of a second after the lid shut, answered INT5 01h from 0 to 350 tenths and INT3 00h at 400 tenths.[^q]

GetTN, GetTD and GetQ gave the same values in every run. GetQ with adr 1 and a point number returns the point's time from the lead-in, so it gives the sector field that GetTD leaves out. The track starts by GetTD therefore lie 9 to 51 sectors before the starts by GetQ.[^p][^q]

Table: Track starts by GetTD and GetQ

| Track | GetTD | GetQ point time | Sector by GetTD | Sector by GetQ |
| --- | --- | --- | --- | --- |
| 2 | 39:34 | 39:34:51 | 177900 | 177951 |
| 3 | 42:35 | 42:35:40 | 191475 | 191515 |
| 4 | 45:42 | 45:42:48 | 205500 | 205548 |
| 5 | 48:34 | 48:34:25 | 218400 | 218425 |
| 6 | 51:24 | 51:24:20 | 231150 | 231170 |
| 7 | 54:12 | 54:12:17 | 243750 | 243767 |
| 8 | 57:55 | 57:55:09 | 260475 | 260484 |
| 9 | 60:59 | 60:59:17 | 274275 | 274292 |
| 10 | 64:06 | 64:06:46 | 288300 | 288346 |

| 12 | 66:22 | 66:22:43 | 298500 | 298543 |

### GetQ and Commands 17h and 18h

GetQ with 0, 1 or 3 parameters answered INT5 03h 20h. With two parameters it answered INT3 02h and then INT2 with ten bytes: the control and adr byte, track 00h, the point, the lead-in time, 00h, the point's time, and a last byte of 9Fh or FCh. The control and adr byte was 41h for points 01h, A0h, A1h and A2h and 01h for points 02h to 12h. Point A1h gave 12h, the last track, and point A2h gave the lead-out at 69:22:03.[^p][^q] The INT2 came 430,561 to 1,747,464 cycles after the command in all rows but the first row of the third run, which took 18,303,510.[^p][^q]

Point 13h is not on the disc. The drive answered it with INT5 and error 40h after 358,111,470 cycles in the second run and 360,047,105 cycles in the third.[^p][^q] Commands 17h and 18h with 0, 1 or 2 parameters answered INT5 03h 40h. Test 04h answered INT3 02h, and Test 05h two seconds later answered INT3 00h 00h in both runs.[^p][^q]

### Reads and Seeks in the First Run

In the first run ReadN answered INT5 with stat 03h or 01h at single and double speed, from sectors 16, 1000, 50000 and 118100, and no INT1 followed. GetlocL answered INT5 80h in every row. During these rows GetlocP gave track 1 at 00:01:66 to 00:02:00 at single speed and at 00:00:10 at double speed.[^o]

SeekL still completed with INT2 in runs 1 to 3 of SK4 and in run 4 up to the inward rows. GetlocP right after INT2 gave a sector from 1 before the target to 2 after it in every completed seek. In run 4 the drive answered the inward rows and all later rows with INT5 and stat 16h, 13h or 11h, which have the shell open bit set.[^o]

Table: SeekL time to INT2 in cycles over four runs

| Seek | Single speed | Double speed |
| --- | --- | --- |
| 16 to 14839 | 19,051,664 to 32,692,060 | 7,350,431 to 81,977,436 |
| 16 to 29662 | 15,878,854 to 22,104,280 | 13,614,944 to 16,222,407 |
| 16 to 59308 | 27,306,344 to 39,062,168 | 19,526,638 to 51,851,696 |
| 16 to 88954 | 23,169,039 to 49,108,640 | 33,802,287 to 58,749,328 |
| 16 to 118600 | 27,956,011 to 34,586,510 | 38,982,043 |
| 1000 to 1001 | 385,328 to 4,004,462 | 189,900 to 191,815 |
| 1000 to 1004 | 1,742,408 to 1,757,484 | 836,208 to 857,851 |
| 1000 to 1016 | 10,793,869 to 11,229,965 | 5,359,958 to 5,383,499 |
| 1000 to 1064 | 6,298,398 to 6,765,232 | 3,339,199 to 3,352,896 |
| 1000 to 1256 | 3,174,176 to 11,755,500 | 3,354,512 to 3,402,416 |
| 1000 to 2024 | 5,504,406 to 14,606,251 | 4,993,820 to 7,055,767 |
| 118600 to 88954 | 14,245,879 to 20,709,934 | 10,184,848 to 13,412,908 |
| 118600 to 29662 | 20,992,432 to 25,345,616 | 15,266,460 to 20,437,403 |
| 118600 to 16 | 31,006,208 to 31,202,668 | 22,469,663 to 22,497,452 |

A seek of 16 sectors from 1000 took longer than a seek of 64 sectors at both speeds. At double speed it took about 5,370,000 cycles where 64 and 256 sectors took 3,339,199 to 3,402,416.[^o] Five double speed seeks outward gave no INT2 within the wait, and GetlocP after them gave a place other than the target.[^o]

### Speed Change and Motor Commands

The second run repeats four times a speed change followed at once by ReadN, then Stop, MotorOn and Init. The times to the first INT1 after a change to double speed were close together in three runs, and the times after a change back to single speed spread from 18,182,227 to 150,746,965 cycles.[^p]

Table: Cycles for speed change and motor commands

| Step | Run 1 | Run 2 | Run 3 | Run 4 |
| --- | --- | --- | --- | --- |
| Single to double speed, first INT1 | 20,457,578 | 22,528,474 | 20,578,341 | 36,083,669 |
| Double to single speed, first INT1 | 150,746,965 | INT5 06h at 134,730,344 | 18,182,227 | 136,003,240 |
| Stop, INT2 | 12,624,528 | 36,490 | 13,504,402 | 12,829,680 |
| MotorOn after Stop, INT2 | 88,547,584 | INT5 03h | 82,233,798 | 67,140,062 |
| Init, INT2 | 5,366,692 | 91,715,538 | 4,893,782 | 4,909,236 |

In run 2 the INT2 of Stop carried stat 02h, where the other runs gave 00h. MotorOn after it was refused with INT5, and Init then took 91,715,538 cycles.[^p]

### Play From the Pregap and SeekP

Play from sector 177801, which is index 00 of track 2 and 150 sectors before its start, answered INT3 02h and sent no report before the Pause. Pause then answered INT5 43h. Stat 43h has the seek bit set. Play from 75 sectors before track 2 gave the same result after INT3 42h.[^p]

Play with track 2 as its parameter answered INT3 42h, and the first report came 63,388,481 cycles later. The reports then came about 4,515,000 cycles apart and 10 sectors apart. They alternate between the absolute time and the time from the start of the track, which has 80h added to the seconds byte. For example 00h 80h 74h is 74 sectors into track 2. That place lies half way between the reports at 39:35:40 and 39:35:60.[^p]

After SeekP to an audio sector, GetlocP gave a sector 1 or 2 before the target at both speeds, and GetlocL answered INT5 80h every time. SeekP gave INT2 1,621,185 to 23,011,137 cycles after the command.[^p]

Table: GetlocP after SeekP

| Target | Single speed | Double speed |
| --- | --- | --- |
| 39:34:51 | 39:34:50 | 39:34:49 |
| 39:34:59 | 39:34:57 | 39:34:57 |
| 39:35:51 | 39:35:49 | 39:35:49 |
| 39:48:01 | 39:48:00 | 39:47:74 |
| 39:33:51 | 39:33:49 | 39:33:49 |
| 42:35:48 | 42:35:46 | 42:35:46 |
| 42:42:15 | 42:42:13 | 42:42:13 |
| 66:22:51 | 66:22:49 | 66:22:49 |

### Audio Modes

With Report off, GetlocL during Play answered INT5 83h 80h, GetlocP gave track 2 index 01, and Getstat gave 82h. Pause after it gave INT2 7,353,297 and 7,469,330 cycles after the command.[^p][^q] Forward sent at once after the INT3 of Play was refused with INT5 03h 80h, and the reports of Play went on. Forward and Backward sent after a Pause were refused the same way.[^p][^q]

Forward sent while Play was running answered INT3 82h. Its reports carry stat 02h in place of 82h, and the absolute time in the first 40 reports moved from 39:40:40 to 40:04:54 in the second run and from 39:40:74 to 40:06:54 in the third. Play with no parameter then answered INT3 82h and reported from 40:30:20 in the second run and 40:36:60 in the third. Backward worked the same way in reverse, and the Play after it reported from 39:44:06 and 39:49:68.[^p][^q]

With AutoPause on, Play from 42:31:40, 2 seconds before index 00 of track 3, gave INT4 with stat 82h after 84,717,281 and 86,771,577 cycles. Getstat then gave 02h, and GetlocP gave track 2 at 42:33:32 and 42:33:27.[^p][^q] With AutoPause off, Play from 3 seconds before the lead-out gave INT4 with stat 02h after 129,348,670 and 131,730,976 cycles. Getstat then gave 00h, and GetlocP gave track AAh at 69:22:03. GetQ point A2h gives the same lead-out time.[^p][^q]

MotorOn gave INT2 after 108,930,323 and 70,099,901 cycles, and a second MotorOn was refused with INT5 03h 20h. After a Play, Stop gave INT2 00h after 3,302,766 and 7,301,383 cycles, and Init gave INT2 after 92,634,323 and 80,370,525 cycles.[^p][^q]

### Data Modes

A Getstat about every 30,000 cycles through a SeekL from 16 to 100000 gave stat 02h at first and 42h from 301,629 cycles on. In 400 Getstats no other interrupt came. A ReadN to 50000 gave the same stats with no INT1, and the Pause after it was refused with INT5 43h.[^p]

Init after a SeekL to 100000 gave INT2 after 19,589,416 cycles at single speed, and after a SeekL to 50000 it gave INT2 after 21,787,741 cycles at double speed. At once after Init, GetlocL gave the header 00:01:72 and GetlocP gave track 1 index 01 at 00:02:00. One second later GetlocL gave 00:01:73 at single speed and 00:01:68 at double speed, and GetlocP gave track 1 index 00 at 00:01:71. Getstat gave 02h and the mode read 20h.[^p]

ReadN from sector 2000 in mode 20h delivered sectors about 450,000 cycles apart when the first INT1 was taken at once. When the first INT1 was held for 2 to 4 sector times, the first sector was the one asked for, and the next ones began at the sector reached during the hold. From a hold of 6 sector times on, the first sector delivered had the header 00:28:58.[^p]

Table: Sector headers delivered after the first INT1 is held

| Hold (sector times) | Headers of the ten sectors delivered |
| --- | --- |
| 0 | 00:28:50 to 00:28:59 |
| 1 | 00:28:50 to 00:28:59 |
| 2 | 00:28:50, then 00:28:52 to 00:28:60 |
| 3 | 00:28:50, then 00:28:53 to 00:28:61 |
| 4 | 00:28:50, then 00:28:54 to 00:28:62 |
| 6 | 00:28:58, then 00:28:56 to 00:28:64 |
| 8 | 00:28:58, then 00:28:58 to 00:28:66 |
| 12 | 00:28:58, then 00:28:62 to 00:28:70 |

### Seek Past the End

SeekL to sector 312150, 150 sectors past the lead-out, answered INT3 02h and then INT5 06h 04h after 289,995,740 cycles. GetTN then gave stat 00h, and Init gave INT2 after 78,176,129 cycles. SeekP to the same sector gave INT2 02h after 29,492,327 cycles, and GetTN then gave stat 02h.[^p]

### Test Subfunctions and Decoder Registers

Test subfunctions 03h, 00h, 11h, 12h, 13h, 14h, 19h and 1Ah each answered INT3 with one stat byte. Subfunction 03h gave 02h the first two times and 00h the third time, and the others gave 00h. Two seconds after 00h, Getstat gave 02h. Init afterwards gave INT2 after 72,814,253 cycles.[^p]

Test 71h reads one decoder register a call. Test 73h with a length of 4 gave 8Eh DCh 00h 01h from register 00h and C0h F0h 00h 19h from register 10h, which differ from the 71h reads of registers 00h to 03h in two bytes and of 10h to 13h in one byte. Test 75h gave 1Ch C9h 08h 30h. These are the values of registers 0Ah to 0Dh.[^p]

Table: Decoder registers by Test 71h

| Register | Value | Register | Value |
| --- | --- | --- | --- |
| 00h | 9Eh | 10h | C0h |
| 01h | DCh | 11h | E0h |
