I've managed to get a good range of emulators up and running, most notably MAME.
(Tangent: the wonderful thing about Bittorrent is that it's made so many things so much easier to find and download online. The bad thing is that they're now much harder to find individually; I was looking for a copy of Altered Beast and wound up downloading an entire 13GB torrent of every single MAME ROM. Fortunately, the download went screamin' fast and only took about a day; unfortunately, 2/3 of it is redundant -- generally speaking, every game comes in US, Japanese, and World versions, and many have multiple revisions -- and quite a few won't run at all. I guess there are tools which will only download specified files from a torrent rather than the whole thing; if anyone can recommend a good one for Mac, please drop me a line.)
And now we come to controllers. I've been using my good ol' PS2/USB adapter for years and it has served me well; however, I now have an abundance of 4-player games I can play through Sixtyforce and MAME. So that means I need more controllers.
I've already picked up a Logitech Cordless Rumblepad 2, and it's proven thus far to be a fantastic damn controller. I'm currently scanning eBay for one of the original Cordless Rumblepads with the six face buttons, which I'd like for Genesis emulation and Street Fighter. (I'd also like someone besides Richard Bannister to release a Genesis emulator for Mac, as I hate him. But that's a Stream for another day.)
So that leaves one more controller I need to get. (Two, if I decide to go completely wireless, which I would like to do eventually -- a TV, a DVR, 4 game consoles -- I've got my GameCube, Dreamcast, NES, and PS2 currently connected --, and 3 computers make for a godawful jungle of wires that I would really, really like to thin out. Four if I go completely nuts and want to do a full 6-player game of the original X-Men arcade game -- vastly overkill in the vast majority of situations, but there were definitely times in college when there were four people playing a game and at least two waiting to play winner.) And I'm looking for suggestions. For all this MAME stuff, I think it'd be cool to get an arcade-style joystick: something wireless and in the $30 range; those $100 X-Arcade affairs are gorgeous but just a little bit too much for me, plus, jungle of wires.
It would appear that Pelican has a wireless arcade-style joystick out for around $30, but I can't find any reviews anywhere for it and I'm not about to buy one until I do. Pelican seems like a decent enough company, though; I spent today playing Dragon Quest 8 with one of their wireless controllers and it seems pretty solid, though a bit mushy in places -- I frequently find myself hitting Up or Down on the D-pad when I mean to hit Right. (Aside: I did not buy this controller and have no idea where it came from; it just showed up at my grandparents' house one day. My pet theory is that, like all the dishes, pots and pans, and silverware I owned in college, somebody left it at one of their rental houses when moving out.)
Anyhow, if you know of a good wireless arcade controller, or any kind of good wireless controller, have some general thoughts on Mac emulation, or just want to talk about how much you hate Richard Bannister, E-Mail me.
