With XeO3 being easy to port to the C64, I started thinking about other 6502 platforms... SNES is one I'd like to lookat, particually as I have a couple of old DevKits AND a couple of magicoms. these were copy devices, but I used to use them for homebrew development as you could squirt code down to them from a PC/Amiga.
So, I started reading up on some old PC Engine stuff, and was trying to find something (outside an emulator) that would let me code for it again. I was hunting for something called TurboRAM which was a prototype device to let you download to the TG16, but I couldn't find anything - I guess its long gone now. But this would be cool, so I started hunting for info on the expansion bus to see whats invloved.
I actually found info on the Cartridge port, and its quite interesting... It's only address+data lines, it doens't appear to be encrypted at all!! This means it shouldn't be too hard to make a RAM card that you can download to! So thats another thing on my to-do list, see if i can hack together a RAM card for a PCEngine, then I could actually code for this great little machine again!
(I also have an old MegaDrive devkit! It should work, but i've haven't used it in over10 years now).
