Geometry adjusted, emulators optimized for 240p. This consumer 14" CRT doesn't show great scanlines but if you play very near is good.
This Blueretro adapter works very good on GameCube slots for bluetooth controllers like my 8Bitdo Pro2.
I learned PSX emulation isn't very good on Wii so not the definitive 240p retroconsole but it covers a lot for very cheap.
Yeah, that's very interesting and also a personal preference but to me good scanlines are always appreciated. I picked this 14" and it looks great but I'm curious to try a slightly bigger model to compare the scanlines experience, I'm thinking about a 20" mostly for 480i gen.
