As PalmBoy just emulates a real machine, and does this not really perfectly, some games need patches. Some patches are absolutely necessary to make a game run, others are only to correct graphical errors, for example.
Some next version of PalmBoy will have a patch database. It will collect all patches known, and it will be editable. Just wait and see...
Until then, this page is quite raw. It will list all the patches I know of. Think of all as preliminary, and: USE AT YOUR OWN RISK!

| Banks | n/a | n/a | n/a | The MBC1 has to be switched into the correct mode (4/32). In the source file "banks.c" add the line "*(unsigned char *)0x6000 = 1;" after the "ENABLE_RAM_MBC1;" line. |
| Madden 95 | 00:0051 | 18 91 00 | C3 E4 FF | MANDATORY! This short branch jumps the 0000/FFFF limit, which isn't emulated. |
| Mortal Combat 3 | 00:0CC0 | 31 44 FF FA FC C0 57 FA | F0 44 B9 20 FB FA FC C0 | MANDATORY! Otherwise you'll lose all your data! Tricky SP handling, which isn't emulated. |

| R-Type 2 | 00:0971 | 80 | 7F | Top line of status stops scrolling with background. |
| Tetris | 00:02F0 | 28 | 76 | Runs much faster. |
| Tetris 2 | 00:23BD | CD | C3 | Not necessary; the developers made a harmless error. |
| Zelda, Link's awakening | 01:6DF0 | 20 | 28 | Title "rolls" better. |
