On all versions, would I be able to use a QWERTY format keyboard? I'm also wondering if on the PS2 version if a USB keyboard will work. I'm asking as info on this game is scarse outside of a review of the game from LGR.

I use a qwerty keyboard (but I am not using the PS2 version due to not being able to find a copy).

I would use the PS2 version in part because of the scarcity of that port, though at the same time I don't know at all if that port is compatible with a USB keyboard

The ps2 version was sold bundled with a usb keyboard (I own the standard and keyboard versions of the game) Both will work using any qwerty keyboard that is usb. If you plan to use pcsx2 you need the plugin which I dont know how to use. SLPS-20123 = Keyboard Bundle SLPS-20124 = Standard

Never knew there was a PC Port. Anybody know where I could buy it or message me a link on Discord to download it? I can't find the PS2 version either. Also, since I use Linux, would it be better to just emulate PS2 and use the keyboard plugin or should I run the port through Wine? I assume PS2 but I'm not sure if the game would end up running better through Wine.

Using a proxy on Yahoo auction Japan is probably the cheapest or there might be a ebay seller but it will most likely cost more.

There are many ebay listings, but usually the cheapest is 100. Yahoo Auctions have spiked around 5000-12000yen (50-120usd), but sometimes youll find a cheap auction (though shipping is not cheap.)

Keyboard plugin is difficult to set up for pcsx2 (most people i know cant get it to work) and im not certain the pc version works on wine.

The risk is yours which you try to use or buy, the pc copy is available if you look hard enough but the ps2 one is impossible to get other than purchase.
