There's this program called SAMA that lets you transfer San Andreas save data to the PC and I would like to know how to use it because I have 69 jumps done and I'm in real need of help finding the last jump?
SAMA will not work on PS2 save files. However, the GTA:SA Save Game Editor v1.0 by Ryosuke will display the jump status properly. The map is a bit small but should be readable enough. I wouldn't trust that application to edit your saves. It was written for the Japanese version (for PC, I think) and I had inconsistent result while editing.
The GTA SA Savegame Editor v2.8 by Paul Breeuwsma can also be used on PS2 save and should report properly, and probably edit the jump status. I've had limited success with editing PS2 saves with this tool, but it was designed specifically for PCv1 and some features will not be compatible with PS2.
For either program, you need to extract and just the .b file from the Codebreaker archive. The PS2 Save Builder can extract the save for you.
Before I forget, if you want to use the Savegame Editor v2.8 on PS2 files you'll need to rename them according to the PC filename format: GTASAsf#.b, where # is the slot number 1 through 8.
You'll need to figure out how to download, install, and run the programs on your own. You might need to install a runtime environment to get some of programs to run. Everything should be documented somewhere at the links provided.
I am not sure how Codebreaker works, I was using AR-MAX. Figure out how to copy your save to your computer. AR-Max would first compress my SA folder, then copy it to a USB device. I would copy the file from the USB device to my computer, and then use PS2 Save Builder to open the file. The compressed .max archive would contain several files; PS2 saves start with the slot number, include the name of the last mission passed, and end with a .b extension (for example, 1 End Of The Line.b). If I extract the save file from the archive I can test it with one of the save editors. Extract is one of the options of the PS2 Save Builder.
