CD as device 0, HDD (formatted as FAT*/exFAT) as device 1, burn CD, boot CD, once files are saved turn off, unplug, copy files off HDD.

You don't need to de-solder them, if you have an ATA CD drive and an ATA hard disk drive.

Which Cyberlead io boards have been dumped so far?

It's just a different key, nothing exciting.

Maybe it's had the bios swapped?

You're right, I missed that he had so few TW02. The board on the right with the SC01 is from a target box. If you look closely you'll see it doesn't have a bios fitted, instead the bios is loaded from an socketed rom on an extra board that plugs in next to it. I assume he has it or it won't boot.

There isn't a board layout in the source for coh1002c, but it's used in the emulation. GAME( 1995, ts2, coh1000c, coh1000c, zn6b, zn_state, empty_init, ROT0, "Capcom / Takara", "Battle Arena Toshinden 2 (USA 951124)", MACHINE_IMPERFECT_SOUND ) GAME( 1996, sfex...

That is the GPU ram, a few games have 1MB but the majority have 2MB. Primal Rage 2 needs 2MB of GPU RAM. You can populate that position and change one of the straps on the board. But what I was referring to was the CPU RAM. Primal Rage 2 comes with 4 x KM48V2104AT which makes 8MB, but every...

Interesting. Unless there is a copy of the bios on the bootleg and some way of overriding it, then I think you'll need the correct one. You could replace the bios, but it's not really plug and play. Anyway, hopefully someone will be able to make observations on real hardware soon. First you...

doh, thanks. how did I miss that. It's a different Bust A Move 2. In countries where Puzzle Bobble was released as Bust A Move, they released the other Bust A Move as Bust A Groove.

The output from both of the cat702 chips are wired together, but when they aren't active the outputs float. If they just captured the data on the output pin, then they would get the output from both cat702. My guess is the outputs get AND'd so as long as the bootleg is outputting what the...

You could cross your fingers for luck and buy some https://octopart.com/cat702-catalyst+semiconductor-13008420 You'll need to figure out how to program them, which might need decapping. I asked http://arcadehacker.blogspot.com/ already, but he's busy.

Only two of the bloody roar 2 roms are dumped. One of the ROMs is for the OKI & the other is for the CAT702 replacement. The CPLD appears to just grab a byte from the ROM and bit shift it out. Only a small part of the game boot is encrypted and so a replay attack is practical. The beasorizer...

That is a shame, I have a reasonable idea how the protection works on these bootlegs but I can't see how it could work on any motherboard. In fact I can't make it work on the motherboard I'd expect it to work with either.

What are the marking on the chips ic353 (bios) & ic652 (cat702) on the motherboard?

The link is dead, does anyone still have a copy?
