Using a CycloDS, is it possible to create a RealTimeSave (RTS) file, copy the RTS onto a PC, open it in a hex editor, search and change the file, put it back onto MicorSD and succesfully load it up in the CycloDS again? Possible problems: Does the CycloDS use any form of error/checksum checking when saving/loading RTS files? Is the RTS a 1:1 memory dump of the memory available to the NDS/Game, or does it include the hook for the CycloDS extended menu? (most likely if its a 1:1 copy of all system memory) Other options: Is there a working NDS Emulator that allows direct memory searching/editing? Using iDeaS, i am able to view memory and manually look through it, but there doesnt appear to be any search or direct edit mode available. Run a standard Windows memory search/cheat tool on a running NDS emulator? Does the emulator store NDS memory in ANYTHING close to the original NDS format? (correct endian, choesive linear format, etc...) Possible Solutions: If CycloDS does use error/hash checking, is the format known? If so, becomes trivial to fire out some c or perl code to read an RTS and update checksom. NO$GBA debug version still available for purchase anywhere? heheh doubtful, but im sure it had direct memory editing. Request: any further info on CycloDS RTS format. Thanks!
