I have a script which takes the disks, applies the corrections and then builds the rom. It's all a single makefile.

Adding R800 is easy, the problem is making FM work meanwhile. Patching the FM to work with R800 is also easy. I have however opted for the hardest route which is adapting the game to work with FM Bios, and this takes some time.

There are going to be more layers in that cake after this is done.

Have you made any progress with this?

If not, you could always opt for the easy route.. Wink

Actually I did! I rewrote the entire sound driver to use the FM BIOS, and it took a long time because there are lots of OUTs spreaded through the code instead of being at just one place. I managed to patch them all.

But work on R800 is not complete yet because the speeches are too fast. I'm going to rewrite the speech driver now to allow any kind of turbo to sound at the same speed.

I know it sound a bit crazy, but since I have an ASCII-8kBytes paged 512kByte flashROM, I kindly ask You if is it possible an ASCII-8kBytes version with some stages and not the whole game.

I could probably fit the entire game in 512kb if you don't mind a loading screen while decompressing. But this is not in the plans right now.

(Metal Gear 2 does that, the fox animation is a loading screen while it decompress data).

Does working with the FM BIOS mean it would be possible to make it compatible with MSX-AUDIO BIOS 1.3? If so, it would be another great use case for the BIOS. Aleste 2's soundtrack is awesome.

I didn't try it yet but it should work with this bios indeed.

(Last night I tried to see how much could I compress Aleste 2, the best I could do was 550kb, which is frustratingly short of the 512kb goal. I think 512kb should be doable with more nights of work but I'm not going to pursue it right now).
