WagnerBrasil Posted December 16, 2018 Author Share Posted December 16, 2018 I tried to modify the rom in FF8 FF9 did not work. I tried to turn the addressing (A12-A11-A10-A9) into binary to make change between the banks, it did not work. Does anyone have a suggestion, what is the correct way to change the bank in this scheme of the board. The files are together Eagle 5.0 Quote Link to comment https://forums.atariage.com/topic/286087-f8-bank-switching-method/#findComment-4178189 Share on other sites More sharing options...

Valdemar Gomes Posted March 19 Share Posted March 19 Estou vendo esta mensagem em 19/03/2024... Houve alguma atualização relacionada ao projeto? Estou a procura de um circuito para confeccionar um cartucho simples, que comporte apenas um jogo de 8k e que possua um Bank switch simples (F8), usando TTL, por serem baratos e fáceis de serem encontrados aqui no brasil. Alguém poderia ajudar? Quote Link to comment https://forums.atariage.com/topic/286087-f8-bank-switching-method/#findComment-5432532 Share on other sites More sharing options...
