The problem goes from mild to major when you have people that aren't technically savvy (or even those that are who have NO CLUE this is a new issue cause it's POORLY DOCUMENTED) reporting working cheat codes as broken, having inconsistent errors based on nightly vs stable builds, incorrectly reporting mods as the cause due to accepted cheat codes suddenly breaking rather than other stuff, etc. The emulator at some point was updated to remove support for this and it broke a lot of compatibility with a bunch of cheats that were written with the 0x prefix. This is something that works in the stable build and has worked prior to 2022.
