Help with annoying lag

Hello, anyone know some kind of solution? When I played few months ago everything was running smoothly with no problems, I even found and installed animated sprites. Now after few months the game lags when in battle, when I hit opponent and their HP is depleting it is lagging. I also checked that out in Zeta/Omicron where I don’t have animated sprites and I have the same problem. Anything has idea what could be the issue? I didn’t change any game settings or anything Btw other emulation games started lagging also, while ETC league of legends and other “normal”, non emulator games run smoothly like always

Are you on mac or windows?

btw this game isn’t an “emulation game” it’s not a rom or rom hack it’s a .exe file

It is windows 7 and I have no idea what seems to be the problem, maybe it would be the best to reinstall windows but I have to much important programs

Try these?

Though if the HP depletion didn’t lag before and it lags now, I’m at a loss.
