Re: Question about "Full Graphics Function"

Sprite disappearing on certain conditions ???

It's been a week that I'm trying to find a bug in my gameplay code about a strange sprite "disappearing" for no reason. I couldn't find any bug in my gameplay code, so I started to try some test on sprite display, and I found that the "bug" is coming from the Megadrive itself, but I can't figure out...

Re: Escape 2042: The Truth Defenders

Thank you :) I'm using my own SDK, low level hardware access using asm routines, and C language for Gameplay. (I use VBCC compiler, the asm interface is much more easier than GCC's syntax) I use Tiled for map editing and my own command line tool for conversion (check my website for tools http://orio...

Virtua Racing Test Mode GameGenie Code

While trying to understand the SVP code of Virtua Racing (I wanted to write my own SVP code, but well, no assembler, and too much headaches understanding the svp hardware) I found a way to get access to the Test mode that Notaz is talking about in his SVP doc. It's pretty useless but here is the Gam...

Re: ASIC Trace Table Question

can someone post a source code example on how to use this rotation feature of the mega cd ?
the official sega sdk documentation is not very crystal clear on how to use it, and I didn't find any open source example of this :/

I switched my Megadrive with both 50/60Hz + USA/Jap switch. I start the Megacd 2 Japanese Bios from the Everdrive in 60Hz/JAP mode. And the 3 games that weren't working before (in 50Hz/PAL) still don't work in 60Hz/JAP :/ So, I guess, this might be an everdrive incompatibility. Jap Games not working...
