Subject says it all. Back in the GBA days, Eurasia would release some hot new game and shortly thereafter VENOM would strike with a +6 trainer. Or Mode7 would have a cool release and the same day Quartex would release a +4 with in-game level skip. Because of the encryption nowadays, it won't be a simple .ips (or .xdelta3) patch anymore, until we're able to run fully unencrypted ROMs. But my question is: is there currently a technical reason we don't see these (e.g. we're able to patch data but not executable stuff) or is it just a general lameness in the scene? Of course they would be for single player/offline use only.
