The emulation on the xbox systems, for it's "backwards compatibility" is unreliable, and in many cases has major glitches or bugs that'll make your game damn near unplayable, such as getting the black screen of death or getting your game frozen. Even now in the current year i'll be playing morrowind on the new xbox series x, and although the graphics are cleaned up, the trade off is unstable gameplay where opening up a tab too quick might fuck up the game. Hell, the game might say "fuck you" and quit anyway.
A direct reminder
>Supported Original Xbox and 360 games will run within an emulator and have access to certain Xbox One features, such as recording and broadcasting gameplay. Games do not run directly from discs. A repackaged form of the game is downloaded automatically when a supported game is inserted, while digitally-purchased games will automatically appear for download in the user's library once available. As with Xbox One titles, if the game is installed using physical media, the disc is still required for validation purposes.
Your system requires wifi to download the game from the store, the system CANNOT read the files from the disk. This is the same with people who own an xbox 360, internet is required (also a new hard drive) to access your original xbox games. Most of the problems actually availible on the 360 emulator for original xbox games have not been patched so if you get the black screen of death its microsoft being fuckers and not you or your systems.
Here's another unpatched bug from peacewalker, on the xbox series x, in the year of our lord 2023
Was playing the secret monster hunter level, and while i was fighting a monster he launched a fireball that gave the game INCREDIBLE LAGto the point where the game crashed and refused to open for a very long while.
Playstation, has NATIVE backwards compatibility. It has the chip that can actually read whatever disc depending on the system. As an example, the ps2 can play ps1 games natively, an earlier version of the ps3 can play ps, and ps2 games. Ps4 cannot play ps3 games. ps5 CAN play ps4 games natively, without emulation. There are problems, games might get bugs that cannot be patched, maybe issues with AA and some games not being playable.
This is a fair warning for those interested in investing in a new console and thinking you can somehow enjoy your older games on newer systems without a hitch.
With that out of the way, how are GB/GBA games handling with emulators? I'm assuming that there might be problems with certian games that use the internal clock as an example like pokemon.
