Have to relive this old thread to compare our experiences.
I'm burning a couple of eeproms with some personal compilations of games in order to test the whole process, the objective is: merge 4 16kB LO ROMs and 4 16kB HI ROMs to be used in a Sukkopera's OpenCard (which allows the selection of 4 16kB banks into any of the hi/lo 64kB eeproms, have to add this hardware heretoo...), and have overall up to 128kB of games in one single card. While composing the first hi/lo couple, had a surprise: I guessed I can use the memory $8000-$FCFF, but that's not the truth, because the operations necessary to transfer in RAM probably touch into $FCxx, so the real available ROM on a C16 seem to actually be 31kB $8000-$FBFF.
Does this match your experience with it too? |
