Subject: Re: [stella] Cartridge dumper again From: Glenn Saunders <cybpunks2@xxxxxxxxxxxxx> Date: Sat, 11 Jan 2003 10:26:07 -0800 |
When dumping a cart with RAM, the cart RAM contents are essentially random. My dumper uses weak pullup resistors on the data bus, so when I "read" from a RAM "write" address, I read $FF. Hence when I write a dump, I write $FF at these locations.
Ok, there's the problem, what's the solution? Especially given that a whole BUNCH of roms (over 2000) are floating around the net.
