Re: Compiling an emulator for enhanced Megadrive

As for compiling, might as well try out M.A.M.E. since it has integrated M.E.S.S for quite some time (so you can run arbitrary ROMs), but I believe they both have the drivers framework in there. Been quite a while since I last compiled M.A.M.E. but what I remember was mumbo jumbo macro magic. I alr...

Re: Compiling an emulator for enhanced Megadrive

And I'd punch you in the face if you removed that :​v (same goes for window plane) Challenge accepted :twisted: Once you figure out how to make good use of them you definitely won't want to lose them. Same goes for extra palettes. And it's easier to figure out. This is also why I had pushed for VDP...

Re: Compiling an emulator for enhanced Megadrive

Yes, you can more or less see that as a fanboy wishful thinking :mrgreen: Concerning costs, I want to remove Shadow/Hilight, I'd be surprised if it wouldn't compensate for added palettes. The VDP would still produce less impressive images than the SNES one (apart the resolution), but I'd be very cur...

Re: Compiling an emulator for enhanced Megadrive

Ni, that's not what I want. MD has enough CPU power for its age and I don't want mode 7.

Just more palettes and more colors, and not so much. Then again something that would have been achievable, at more or less the same price.

Re: Compiling an emulator for enhanced Megadrive

Yeah, System C2 isn't compatible in any form. Not only there's no Z80, the YM2612 is at a different address, I/O is completely different, there's a watchdog, CRAM is 68000 mapped, it uses the VDP's own EDClk instead of the external one the Mega Drive uses, it uses the VDP's DRAM mode (which is an i...

Re: Compiling an emulator for enhanced Megadrive

There are much more analogies between the C2 and the Megadrive, than between both of them and the System16 (the idea that MD hardware comes from System16 is likely a bad interpretation, or a "commercial" claim). But indeed, if there's no Z80, retrocompatibility is doomed... So... compiling GenesisPl...

Re: Compiling an emulator for enhanced Megadrive

Is there a known MD emulator handling System C2, and can we find documentation about those extra abilities ?

Also, is the system C2 backward compatible with MD ? (will a MD rom load and run normally ?)

Re: Active Disassembly - Post Processor

Thanks.

I downloaded Peasauce last week, trying to play with its source. Didn't know it was aimed to replace resource though.

Re: Compiling an emulator for enhanced Megadrive

Still can't compile Genesis Plus.

I find lines like :

Code: Select all

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
M68KMAKE_PROTOTYPE_HEADER
in m68k_in.c

How is it supposed to be correct ?

Re: Compiling an emulator for enhanced Megadrive

Trying to compile Genesis Plus. Opened file in code::blocks. * installed SDL-1.2 lib and added path in linker and include options * same with Zlib * same with Allegro-5.1.X.X * renamed uint8, 16, etc. as uint8_t, uint16_t, etc (which seems to be the standard names now) It doesn't compile. I suspect ...

Re: Compiling an emulator for enhanced Megadrive

Dgen is a very nice emulator to modify. However, we've had this same discussion on Nesdev about NES and SNES enhancements several times. The conclusion each time is that it doesn't make any sense. If you want to make unlimited games, target a modern platform. It is precisely not the case : I just w...

Compiling an emulator for enhanced Megadrive

For some time I have had discussions, noticeably with Stef, about an enhanced Megadrive. Just simple enhancements, such as : * dissociated palettes for sprites and backgrounds * 12 bits colors like Game Gear (or even 15 bits) * anything else... (128 KB VRAM...) Those modes would be selectable by a m...
