Can I Patch Game Cardridges?

[CrazyMaxx]

I have bought Super Mario World Super Mario Advance 2 and my Question is:

Is it possible to Patch my official Game with my Dslite and Flashcard? Like the Savetool... I would love to apply the Color patch ips

In theory you can use an action replay cart for that with a lot of hard work, but a gba flash cart would be way cheaper for you.

I have a Supercard Dstwo Flashcard for Nds... Not a Action Replay... My hope was there is a way with some programs for Dstwo to Patch it

Thank you for your fast Reply

Not in the way you're thinking.

On physical cartridges, games are stored on flash storage called ROM, AKA Read Only Memory. The important bit here is the "Read Only" part, you cannot write any data to a ROM chip because it's simply not supported. Patches change the data in the ROM, so therefore you cannot patch a physical copy of a game because you cannot write to the ROM.

The only way to play patched ROMs on a physical console would be through the use of a flash cart, like from one of ever popular Everdrives from Krikzz.

In that case, just apply the patch to the rom file (If I remember correctly, you can rip the rom from your own cart with some DS homebrew. and run the patched rom with the DSTwo gba emulator.

you can also play it on emu because it is very easy to apply cheat to it ...... finish it .... and then transfer your finished save to file to your real game cartridge.

I finish most ds Pokemon games on flash cart to use exp x4 to finish the games quickly and 100% catch rate and then convert the save file to raw save file to transfer it to real ds games via app called checkpoint.

Actually, it is quite possible to patch/modify read only memory but in order to do so you would need a device that is connected between the game cart and the system. As an example, the Game Genie was fully capable of modifying ROM data which is why you could have a true infinite lives code (by replacing the "subtract 1 from $LIVES with a NOP) while the action replay or gameshark version was really a "always have X lives" code (continually overwrite the RAM address where the number of lives is stored) since those could only modify RAM, not ROM. As far as I know, no such hardware exists at all for the DS and I know of no cheat device that lets you use IPS patches rather than just a handful of codes.

In theory you can use an action replay cart for that with a lot of hard work, but a gba flash cart would be way cheaper for you.

I am pretty sure that an action replay only lets you modify RAM, not ROM. You would need something like the Game Genie only powerful enough to handle IPS patches not just a few (three or five) patch codes.
