  1. This i have found but it not work for me. maybe someone understand it. i do this but game not save inside the rom The ROM --> SRAM loading is basically done to be able to save without battery. Over all the behavior of those roms is as follows: During Boot: Load ROM Area to SRAM During Save: Save to SRAM --> Copy SRAM back into ROM area and do some voodoo calls to persist. However: After a bit of fiddling here and there, I came to the following workflow: 1. Apply GBATA SRAM patch as normal 2. Search for Bank switching pattern in a Hex Editor. For FLASH1M_V103 the pattern is: Code: 054B 8021 0902 0922 1206 9F44 1180 0349 C302 C918 1180 7047 3. Replace it with pattern: Code: 054B 8021 0902 0922 1206 9F44 9021 0905 0000 0000 0870 7047 Obviously this is different for different FLASH types. I will try to create some automatic patching script in python or C this weekend that should cover other FLASH1M versions as well. ---- Technical explanation: For some reason, GBATA SRAM patching does some "voodoo" bank switching that does apparently not work on real cartridges. To make it work, I removed the "voodoo" parts and simply say: Write $BANKNUMBER to 0x9000000 And that's it Can you also do that this tool insert a save? Scan where it is and replace it?
  2. I hope you can help me. and also like to help me. I have some Pokemon Hacks, and i like do it on a bootleg card. my games all cant save i search much on google all say to me i need a "sram patch". i try it from gbata but also not work for me. so i search more and found on gatemp, i need do with hex editor change some code that the game save into the rom. i try some but also not work. can you tell me what i have to edit for this rom to make it work?
