+Gemintronic Posted February 16, 2022 Share Posted February 16, 2022 Seems like the PAL sources tend to use up more ROM in bank 2. Why is that? Quote Link to comment Share on other sites More sharing options...

You can get more free ROM if needed if you build setting the ORIGINAL_ROM flag to FALSE. This will eliminate a lot of garbage data. The stats I reported are from the original ROM builds. Removing the garbage data should give you... *** 417 BYTES OF ROM FREE IN BANK0 *** 24 BYTES OF ROM FREE IN BANK1 2 Quote Link to comment Share on other sites More sharing options...

Sounds like a simple case for adding this to the PlusROM High Score Club I was able to make the changes for the PlusROM HSC, but it toke me some time. Free ROM space was not the problem here! The ROM switches to attraction mode when the game is over and this is the situation where the scores have to be sent. Unfortunately, it uses the same code when it switches from the title screen to attraction mode. So to prevent the ROM from sending a zero score (or the last score) every time it switches to attraction mode, I had to find a way to distinguish the two cases. 1 Quote Link to comment Share on other sites More sharing options...
