Oddly enough, more than 20 years after the game's release, there still isn't a mod (or at least, I haven't found one) that remakes the arcade minigames in HD. Today, I spent the afternoon making one. The textures were generated with AI.
Just drag and drop the files into your GTA SA main directory (be sure to back up the original files, just in case).
Feel free to use, modify, and redistribute the files however you like — no restrictions.
