So I bought a new ML-1220 battery, soldered it, everything works fine (no "battery has run dry" msg in Pokemon Ruby) but when I save the game and turn off the DS, the save file is being created but instead of "Pokemon Ruby Version.sav" there is something like "Pok!!!monRuby Varsio.sav" and GBA Exploader doesn't even see this save. I have turned off multi save. Here's link to the old thread (before I bought a new battery): https://gbatemp.net/threads/m3-gep-rtc-stopped-working-after-3-months.388310/ Update: Tried LeafGreen and save didn't even got created. But when I save and soft-reset the game then it's all good ofc.
