If you have GenesisSoftwareManual.pdf, that new header system is documented there, I think as one as the memos (I always mix memos and addenums, but I think this one is a memo :P). Go and check. Anyways once I made a poll and people liked more the old system, including myself, so I think I'm gonna s...

Well, let's start with the 2gen thingy. Just so you know, 2gen would be the second generation of Mega Drive games, probably most of it homebrew :P I want to remark that Ninja Fight isn't what I would like from 2gen, it's too simple, I want 2gen to prove that the Mega Drive can do wonders with the ha...

In theory , all games work even with the MCD and the 32x attached. However, if a specific game doesn't work with them, don't get surprised, that's what I mean. I think the main reason all games (except VR) work with the 32x is because they don't have any oddities. If the MD was like the SNES and al...

Sonic 3D just made the level select cheat completely dumb

That screen appears because the vectors for the exception interrupts are set to a subroutine that goes to the level select, nothing more >_>

Update. Press B It's just the animation through, no effect still. Yeah, I'm lazy I gotta update my page too >_>

I saw normal cartridges failing to run on the 32x (one Sonic 3D cart from a friend doesn't run on the 32x with good video while without it it's all OK, while normally Sonic 3D doesn't get affected). Simply you can't expect a non-32x game running with the 32x attached. Same goes with the Sega CD, don...

The entire header is a suggestion. Only the first four bytes really matter. Through some emulators don't like invalid headers (I tried to put something at 1E0 and all emulators crashed the game by invalid header being read >_>).

I thought Sonic 3 had SRAM at $300000. Imma check later. Anyways, seriously, am I the only one that expects emulators to respect the header? Sega is very clear about how SRAM is to be specified in the official docs >_>

What about the SRAM trick? If you put an invalid address for SRAM in the header, you'll immediately know if there's an emulator or not (whenever it emulates SRAM or not).

How do Fusion or Regen emulate SRAM? Do they treat it as slower than normal RAM or as fast as it? You need to write $01 to $A1301F (well, $A13000...$A130FF) to enable SRAM at $200000....$20FFFF. Beware, only 64KB SRAM, 2MBytes SHOULD be emulated (only emu that does it is Genecyst). The speed SHOULD...

You added the supervisor and user 68k modes to Regen and no other emulator supports it because no games use it. No it does not . What led you to believe that? I guess you are talking about address error exception emulation. Well Tiido made a program that used this flaw in emulation so I added it. A...

>_> Adding question by the way: can somebody confirm me if changing the scrolling registers (VDP mode-4) in the middle of a scanline works? I know some work (like the backdrop color register), some don't (like the enable display setting). I want to know if those do (the scrolling circuit shouldn't b...

@ Sik and King of Chaos If I see any game that relies on it and runs correctly on real Genesis and not in Regen then I'll add it. You added the supervisor and user 68k modes to Regen and no other emulator supports it because no games use it. So I guess it would make sense :P Besides I've just thoug...

Stupid question: does Regen support VDP's mode-4? Yeah, the Master System mode. I know no MD games should be using it, but now that I come to think on it, things such as the stretching part of the Nine Pixels demo can only be reliably done in mode-4 because the scrolling is done using the registers ...
