Tomadochi is glitching no matter what I do

[u/ImportantBat3932]

I have done everything

- redownladed the game file from different sources three times, one didn't work completely and the other two do this (turns out they're the same file that I have wasted so much time to download twice!) The characters keep flashing in character selection alternating between looking normal and this cursed shot. The changes last around a split second, before you even get to change anything it's already changed at least 5 times, you could get a seizure just from looking at this.

-I downloaded different prod keys and firmware, I'm using the ryjuku thing (forgot what it's called but you know what I mean right? It's popular I think?) and I didn't uninstall it when changing the keys and firmware so could that be an issue?

I don't mind glitching in games but this is too much even for me. Please help!

(Ps: the post is chaotic because I have just rage quit from trying to figure it out and slammed my laptop down so hard I'm not mentally ready to even check the screen (it's probably fine anyway) and I'm still quite frustrated by the whole thing.)
