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

this is indeed a very good idea !Gerrie wrote: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.
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
How about improve http://en.wikibooks.org/wiki/Genesis_Programming instead of creating new Wiki?
