Would a little sneak peak video at Dai Ou Jou emulation be too much to ask for?   

[iq_132]

So... Mr David Haywood (Haze) managed to figure out enough of the protection scheme used by ketsui/ddp3/espgal to get them all working (for the most part) quite well.

Anywho, here's a video of ketsui's first level (and yes, I suck, I know).

Sweet! Oh, and congratulations on the remarkable feat, having emulated the "inemulable", now bring on The Gladiator! Any technical detail on the actual protection scheme used?
Oh, and nice run there

The Gladiator runs the entire game on the ARM.

The ARM has internal ROM containing important code

The internal ROM needs dumping, but it is read protected, even against native code.

As I've said on my site, all the IGS produced games are protected *properly*

You got lucky with the Cave titles, they barely even touch the protection, even the weakest protection IGS did on their own games is stronger.

Oh, and for PGM2 there is no 68k (or any CPUs on the motherboard) the CPU is on the ROM board, and again is probably some kind of ARM with internal rom, because the games boot with 'program error' if you remove the program roms.  The chance of those being emulated soon is pretty much 0.

The Gladiator runs the entire game on the ARM.

As in switching roles between the 68k and the ARM7 or using the latter for every task?

From what I can see the 68k does very little apart from send the sprites / tiles to the screen, the main game loop / code runs on the ARM.  That's why the main CPU rom is only 512kb, much smaller than most of the other games.

Thanks Haze and IQ. Thanks for the latest blog post too Haze, that's fascinating stuff and I can hardly wait for the next installment. You should write a book on the history of mame from "the inside".
