Subject: Re: [stella] Game developers input wanted for 7800 Ram Cart From: Glenn Saunders <mos6507@xxxxxxxxxxx> Date: Mon, 07 Apr 2003 23:43:58 -0700 |
I read the patent. It made me dizzy. The easiest thing to understand for me was the source code for the "stella 1.3" emulator, files "CartDPC.cxx" and "CartDPC.hxx". Basically it's F8 with three extra whiz-bangs; an extra 2K of graphics data, a random number generator, and a music generator. The first two (graphics and random number) are simply table lookups, and shouldn't be too hard to do in an FPGA or large CPLD. The music generator I think might be tougher, but I could be wrong.
