There are a few changes I would like to implement in Super Mario All-Stars (SNES), two of which are high priority and the third is just a "would be great, but if it's not possible it's no big deal."
1. I want to make it so Fire Mario reverts into Super Mario when taking damage, rather than turning into Small Mario. This is to maintain consistency with the NTSC version of Super Mario Bros. 3 and all modern 2D Mario platformers since Super Mario Advance.
2. I want to apply the "Brick Fix" patch for Super Mario Bros. and The Lost Levels that can be found on this website, that makes Mario's physics when jumping up into a block match the NES version of those games. This patch already exists, but I don't entirely know how to merge it with another patch that would include change #1.
3. If possible, I would like to make it so upon starting up the game, it will skip past the All-Stars title screen and game select menu, skipping straight to the title screen of Super Mario Bros. I already have SMB2 and SMB3 on my SNES Classic Edition in their Advance port forms, so having the SNES versions of those games is sort of redundant.
If anyone knows how to implement these changes or knows a better place to find information, that would be very much appreciated. Thank you.
