neat didn't know rpg games can work on it
SD plays wonky with RPG maker games. SOme work perfectly, some are unplayable, just have to give it a try and see. If it doesn't work it isn't likely to.
I've honestly played a ton of the Kagura games on here with no issue, it's usually the other vendors like Mangoparty or whatnot that have issues.
Top of mind just Dark Hero Party (no Midi support), Nephilim Hunter (no Midi support again), and Into the Nightmare (text overflowing) have been problems recently.
I completed both RPG Maker (including wolf engine) and non-RPG maker games too, including titles like Apostle, Blazing Aries, Brave Alchemist Colette, Demon Queen Melissa, Evenicle, Evenicle 2, Enatus Radi, Fall in Labyrinth, From Frontier, Haitenai RPG, Last Embryo, Magical Girl Celesphonia, Scarlet Demonslayer, Seed of Evil, Tear and the Library of Labyrinths, The Winning Secret of the Newbie Strategist Princess, Take Me to the Dungeon, Tower of Ardia, Treasure Hunter Claire, and Yamizome Revenger on Steam Deck.
I've even had good success with getting VNs like Boob Wars 2, Beat Angel Escalayer Reboot, and Alchemist of Ars Magna to work with minor tweaks.
Just no luck with getting midis from RPG Maker games to run or the fonts to change.
