The original and best version of my poor, precious Deadly Premonition is still locked to Xbox consoles (though the fact that Microsoft included it in their back compat program was nice of them). Every few months I update Xenia and check if it’s gotten any better but the graphics are still busted.
I’ve been playing the Gears of War games, and while Gears of War 2 was pretty much perfect with only a handful of crashes and few misbehaving minor graphical effects, Gears of War 3 has a massively annoying issue where loading a checkpoint during most levels will completely fuck the game’s scripting and softlock you in various bizarre ways. It also crashed more often which synergises wonderfully with the aforementioned checkpoint problem. You basically need to finish most of the game without dying (or crashing) once
Gears of War Judgment doesn’t have the checkpoint problem, but instead has an issue where after the game has been running for about five minutes, textures begin failing to load, making the game look increasingly psychedelic:
At least it runs nicely and doesn’t crash 
Original Xbox emulation is still pretty hit and miss too. One moment you’re playing something on XEMU and it looks incredible upscaled, then something like this happens:
Not disparaging the devs who already work on these emulators, but it’s clear Nintendo and PlayStation projects have (understandably) way more people working on them
It’s annoying trying to convince people that the original 360 version of DP isn’t “janky” or “so bad it’s good”. It’s just a good game with some weird design decisions. All the bad ports have completely warped how people view the game.
Precisely. The combat was certainly always a bit clunky though since it was added at the publisher’s insistence. The later rereleases tried to “fix” it by just permanently enabling easy mode. DP was also definitely a bit dated designwise compared to games in 2010, which works out just fine since hearkening back to the PS2 is Cool and Good
