Trial of Mana's translations in Collection of Mana uses a hi resolution mode for rendering text that creates noticeable artifacting when using screen filters in e.g. RetroArch if the core changes the screen buffer size to accommodate it. It's a really impressive romhack; they really abused the crap out of the SNES to pack in all this text.
Evidently Tales of Phantasia and Star Ocean were both 48m SFC cartridges, but both were never on SNES. The largest outside of Japan was 32m.
