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...

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.

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...

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...

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 ?)

Thanks.

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

Do you have any tutorial about ressource ?

Still can't compile Genesis Plus.

I find lines like :
in m68k_in.c

How is it supposed to be correct ?

Yes I had figured But I can't find anything about it on the web...

What is this EMD thing ?

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 ...

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...

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...

So it means a C compiler keep exactly track of which registers is used by a function ? Concerning the VDP_waitVSync() code : yes the control port adress is stored in a volatile, but I don't understand why here. There's no call to any function in the loop, so there's no risk for the register used to ...

I've been told on sega-16 board that in some models of Megadrive, some aspects were enhanced (palette, colors ?) but nobody ever used it.

I've never heard about that, and my interlocutor doesn't remember exactly which models and which aspects...

Do you know more ?
