Hey guys,

I was wondering if anyone knew what the correct ROM_LOAD address should be for the CDTV BIOS "cdtv13.rom".

It's currentlly:

ROM_START( cdtv )
ROM_REGION(0x200000,REGION_CPU1,ROMREGION_16BIT) /* for ram, etc */
ROM_LOAD ( "cdtv13.rom", 0x180000, 0x80000, CRC(42BAA124))
ROM_END

As I think Justin's mentioned before, it would appear the CRC is correct, but that ROM definition causes a size error (ROM size is 262,144 with a CRC of 42BAA124).

Does anyone know the correct details? I tried emailing the maintainer (Ernesto Corvi), but the address is long dead (no great surprise).

Anybody had any more thoughts recently about the test driver issue BTW. IMO it might be a good idea to have a spring clean of all the highly prelimanery drivers (this being a good example), and enabling the rest. Might encourage some development of the previously ignored test drivers. The most broken TD's are likely to require a complete rewrite by the looks of them anyway.

Thoughts?

I might end up resurrecting the Amiga driver because in the last few days, an Arcadia driver (an arcade system based on Amiga 500 hardware) was submitted to MAME. This driver was essentially a resurrection of the long dead MESS Amiga driver, so it shouldn't be much work to back port the MAME driver on to MESS.

Similarly I've done some super-preliminary work on using MAME's ST-V stuff to resurrect the Saturn driver, but I don't have anything submittable yet.

Also, don't forget the Max-A-Flex driver which was recently added to MAME. Those games run on an Atari 600XL, which isn't in MESS yet.

The max-a-flex driver was based off MESS' atari 800xl driver. There isn't much difference between the 600 and 800, I think the 800 had more RAM or something.

IIRC the max-a-flex driver is more accurate over the MESS original - some core features were added to allow ANTIC to halt the CPU and all that good stuff.

There were a few additions and tweaks to the ANTIC and GTIA code when it was adapted for use by the Max-A-Flex. MESS then inherited these enhancements, so there is probably some software that works now that didn't work before.
