bruddog Posted February 5, 2016 Share Posted February 5, 2016 Found another TINY bug that is VERY unlikely to have ever been noticed. When the game transfers a playbook from the one you edited in team data to the one saved in the season info it first writes to a MMC3 control register that allows the SAVE RAM (SRAM) to be written to. This is the LDA #$80, STA $A001 sequence. After saving the playbook to SRAM they should have done a LDA #$C0 STA $A001. This disables writes to SRAM to prevent bytes being accidentally changed by during power down. However in redrawing the playbook with the new play another routine ends up doing the LDA #$C0 STA $A001. sequence so either a cosmic ray would have to change the corrent SRAM byte in the tiny amount of time or you'd have to power down the device literally right after pressing "A" to save the new play to try and cause and SRAM corruption.

This is just another @bruddog archeological code dig. segathonsov 1 Quote Link to comment Share on other sites More sharing options...
