The size of ROMs really won't get too much bigger anytime soon. Either that, or Vanilla Ice will somehow incorperate emulation into his newly revived career. I have a good collection of roms, but roms are beginning to get hard to find. I think hat emulation will go on, but it will have to be pushed WAY underground so far under that I think that only dedicated BBS systems will be able to get away with it. I don't won't to have to call some international number and connect at low speeds just to get roms, I don't think I should have to do that.
Emulation is here to stay, dammit.
Well for starters I think on the actual emu side will stay much the same. Old emus will be cancelled while New ones will ne started. I see More Qualtity work like MaMe and Kgen and agin Hopfully the Reture of SNES9X with full super FX suport. I see roms ingeneral being a little harder to find but still out there. The buzz of the machine, the burnt-in high score numbers, and with my friend Trixter's Arcade Ambience sound loop, you can hear people yelling, pounding too hard on buttons, and Journey in the overhead speakers.
