Re: Play Game Gear Games on a Mega SG with Mega SD? Possible?

It's currently not possible because the way the megasg will detect the GG adapter is currently unknown. Once it's released, we'll need to simulate it with megasg, provided it's using some standard pins, or ask analogue for a way to enable it bu writting to some special register or something.

Re: Technical differences

Yes, MegaSD takes the WordRAM access restrictions into account, but to have a proper accurate result, you'll need to disable the "Graphics Scaler Speedup" option in the menu. Disabling this option makes the wordram latencies behave like original megacd, and also makes the wordram restriction in 2M m...

Re: Any source for Sega CD cheat codes?

I generally use gamehacking.org

https://gamehacking.org/system/scd

Look for cheats in raw format. Megasd accepts only cheats with addresses starting in FF (ram cheats)

Re: Feature request: digital-to-digital audio

That's currently not possible because on the cart connector, only the 2 analog audio input pins are available, and there are no free pins for a digital audio transmission.

Re: Neo Sd Pro won't load

Did you place the cdrom data (cue + bin files) in a folder with the same name than the cd neo file?

Re: Graphics Glitch in Neo SD Menu and in game

That happens in games that user raster interrupts, because the in game menu button check eats some execution cycles and causes misalignment of the raster effects. If you disable in game menu trigger, they will work fine.

Re: New system menu options

Well, the "Graphics Scaler Speedup" option is mainly related to the graphics chip in the megacd that does scaling and rotation. MegaSD memory is much faster than the original megacd DRAM memories, so accesses can be done faster, and also, megasd can do some tricks to avoid reading data if it knows i...

Re: Graphical artifacts when using Mega SG

There seem to be little glitchy pixels (I think I saw some light blue coloured pixel sparks in the SEGA logo dark blue), but that's not generated by megasd, it's generated by the console VDP, so it might be some power issue, or maybe HDMI cable problem?
