Yeah, model 1 is the best BIOS to use. And try right clicking while in fullscreen and the menu *should* appear.

the menu won't appear in 320x240.. it does in 640x480 at least.

Before I forget, here's a small bug (also in Regen):
In Micro Machines 2, when J-CART is enabled, the track picture (before entering a race) is replaced with a zoomed micro machines logo
I've had hard time analyzing disassembled code to figure why but it seems it is related either to EEPROM or JCART timings (when either one of those is not emulated, track picture is fine)
I somehow fixed it by changing the way TH values are returned for J-CART: always returning 0 for TH2 (bit14 of JCART address) fixed it (this clears a flag in RAM which later triggered bad VRAM writes)
this is probably wrong and a nasty hack but that could maybe give you some hints about how to fix this issue

No, it's probably absolutely correct, and also probably didn't happen in whichever version i first added J-CART support to. Well found, Sir.Eke wrote:this is probably wrong and a nasty hack

Sorry for the offtopic:
About sharing technical information. What about setting up a some sort of Wiki were we all can submit technical information about various Sega systems ? That would give all of us a good knowledge base without the need for sharing code.

this is indeed a very good idea !Gerrie wrote:Sorry for the offtopic:

I don't really know how that kind of stuff works but maybe starting explaining each sub-section (VDP, YM2612, MEMORY MANGMENT...) based on official documentation would be a good start
then anybody could add its own findings or undocumented quirks

If it needs hosting (or mirroring) I can give the space. I really suck at web stuff so I dunno if my host has the "right" stuff installed (ASP,PHP,MySQL etc..) to support installing of wiki.

How about improve http://en.wikibooks.org/wiki/Genesis_Programming instead of creating new Wiki?

I know you guys dont want to release the source code for the emulator but would you ever considure releasing the source for the ym sound core ?
thanks
thanks

I don't honestly see Snake ever releasing any parts of his source code (it's his right to not do so). I'm sure it's fair to assume that since he's never released any source code, he probably never will.

Running in the wrong mode? I've seen this kind of thing before. I'll try to figure out what's going on here. 
EDIT: Your right, I can reproduce this. Try posting this on the Kega forums on the Eidolon's Inn website - there's a better chance Snake will see it there.

It's definitely a corrupt palette (multiple entries). Hard to say but, knowing Steve, it's probably an easy fix.

edit: nevermind, it was caused by render plugins.
