Intellivision Lives PS2

[kjetil-f]

I found this scrip on how to extract ROMs from the PS2 version of Intellivision Lives.

This is probably quite trivial, but does anyone know how to actually utilize this script?

[hadess]

On Linux, it's pretty straight forward.

Compile the binary:

$ gcc -Wall -o intellivisionlives_extractor src/intellivisionlives_extractor.c

Mount the disc rip ISO so the files on it can be accessed:

Run the compiled binary on the gameroms.rez file:

$ ./intellivisionlives_extractor /run/media/INTELLIVISION/resource/gameroms.rez

[hadess]

It extracts the following ROMs that are detected as matching the no-intro ROMs:

Those are games split off from "Learning Fun II" or "Word Fun":

Crosswords.itv
MemoryFun.itv
WordHunt.itv
WordRockets.itv

The following ROMs were not recognised but seem to work:

Armor Battle.itv
FactorFun.itv
Math Fun.itv

I don't know what that file that gets extracted is for:

Magic_Carousel.cfg

I also found one of the ROMs for emulators in another file: https://gitlab.com/hkzlab/intellivisionlives_extractor/-/merge_requests/1

[mjBrickman]

The bios files exec.bin and grom.bin are located in the SLUS_208.30 file and are slightly different from their original versions as I believe they change all references of Mattel. Exec.bin is in a different endianness than usual and needs to be fixed. I figured this out many years ago before I got into programming and only know this much now from my notes.

[mjBrickman]

To find exec.bin search "04 00 12 01" in a hex editor in SLUS_208.30. This is where it starts. The length is 8192. The format of the file when fixed is "00 04 01 12 ..." with every two places being swapped.

[mjBrickman]

grom.bin starts at offset 461140 in the SLUS_208.30 file and ends at offset 463487. This one works the way it is.

[DrAzathoth]

To find exec.bin search "[04 00 12 01](tel:04 00 12 01)" in a hex editor in SLUS_208.30. This is where it starts. The length is 8192. The format of the file when fixed is "[00 04 01 12](tel:00 04 01 12) ..." with every two places being swapped.

Could that be in little endian format?

Could that be in little endian format?

16-bit byteswapped. I implemented it in https://gitlab.com/hkzlab/intellivisionlives_extractor/-/merge_requests/1

If somebody knows how to download an ISO (not a cue/bin) of the US version, let me know, I'd like to verify that my code works on that version, and implement automatic detection for the ROM extraction.

[mjBrickman]

I got grom.bin extracted from the US version by changing GROM_OFFSET to 0x70A80 in the code.

[mjBrickman]

I got exec.bin extracted from the US version by changing EXEC_OFFSET to 0x06EA80 in the code.

[hadess]

Thank you for those offsets.

I've updated the MR to support extracting the system ROMS and the games from the US version, without the need for a flag or option.

I only ran into differences with "Armor Battle" and "DunVoo". The changes in "Armor Battle" are small enough, but the ones in DunVoo are pretty big (the size is double that of the euro version).

I think that's as far as I will go with those changes. I just hope that they will eventually be merged.

I really appreciate that my question sparked this discussion, and ended up with the updating of the entire script. It's been a while since I've played around in Linux, so I haven't had the chance to test this out in person just yet. But will do when time allows.
