Re: How does the Genesis handle resets, compared to Nintendo consoles?

Someone experimented with this method years ago with success also, I think a person named Jorge Nuno first proposed it.

Re: Why did Sega CD games have lower quality non-music samples than Genesis games?

One problem is that the MD side sound becomes crippled in MCD environment. Due to timing problems Z80 can no longer access what normally is cartridge area so it becomes confined to its little 8KB sized world (and timing problems prevent 68K RAM from being used too, reads do not work and writes produ...

Re: SNES won't turn on

The WRAM chip needs to be replaced, it has an internal short that cannot be fixed. When you desolder it, you'll probably gain 5V everywhere gain but RAMless machine will not work...

Re: SNES Doom Source Released! Now What?

I imagine the stage is probably 25FPS in 50Hz, the ~16% extra CPU time per frame and a whole lot more DMA time will help a lot in things like that. All the 3D games will run a lot faster in 50Hz compared to 60Hz just because of these things.

Re: How does the Genesis handle resets, compared to Nintendo consoles?

I imagine SNES games always do full init upon reset. It just was in Sega software guidelines to differentiate soft and hard resets and this leads to the problems you observe. You could perhaps patch the games to always do full init. Majority test controller port pin directions as they are set to def...

Re: How does the Genesis handle resets, compared to Nintendo consoles?

There are two resets on MD, !MRES (power on reset) and !VRES (soft reset). Games can and do differentiate first reset from succeeding ones and generally do not do full initialization upon a soft reset. You are supposed to have a menu program that is ran every reset that does some sort of initialisat...

Re: Audio Receivers “Calculating” Stereo

There's no such thing going on on any game console output connectors. You do see such things internally in FM receivers and vinyl cartridges.

My thought is that there's not enough people around to make a "festival" lol

Re: HDMI separated audio?

There are things called HDMI Audio Extractors for sale on places such as ebay, but I don't know how well they are going to perform and if HDCP is going to become a problem with them.

Re: [demo] SNES Sonic

MD (and SMS for that matter) has no sort of support for anything but 4bpp tiles, all the BGs and sprites use same data format.

Re: What chips should be in that PCB?

28pin PLCC part doesn't seem to match any display driver chips that google could show me... I thought maybe the 44pin PLCC is an Altera MAX7000 part but power pins do not match, also Lattice Mach1/2 chips have different power pins too...maybe Atmel has anything that might fit... Last one looks like ...

The original one can be alias of whatever ends up being the new one, so that all old links can still work, or at least I think it is possible to do.

Re: The learning process

I do read up a bit first on what I'm getting into so I know what will I need to achieve something, but actually doing things will be hands on trying out stuff and seeing how it works (or doesn't). Over time all the building blocks are learned and rest is just assembling them to build the house lol
