Just wondering everyone's opinion.
Been playing on 512x480 and it looks pretty good.
To answer your question: Do not use ePSXe. Use far better alternatives such as pSX or pcsx-r (but this one might not work with some mods because it's too accurate for them).
As far as resolution is concerned, FFT is rendered in 256x240, and stretched to 320x240. It is supposed to be 4:3, if you don't, things will not look as intended. And if you do decide to not play in 4:3 because it looks "prettier", you better not be posting about graphic issues for some mods because: your settings are wrong.
Never had used another emulator, just DLd pSX and seems very smooth so far.
Thanks!
