how about these!!
in no particular order:
Raptor: Call of the shadows (DOS, windows port is now available but seems to run slower... has a life bar but it's still pretty hard... cool weapon shop thingy)
Starfire (DOS, very cheap 8bit looking game, it was actually pretty fun when I was younger, havn't played it since... It's a gg)
Stargunner (DOS, side spacey side scroller game with pretty nice graphics)
Tyrian (DOS, doesn't run on my comp too good with an emulator so I can't say, I missed out on this one back in the dos days
Overkill (DOS!! It was alright, kind of like tyrian if I remember correct as you get a shield and stuff? well, it was pretty fun)
Major Stryker (DOS, this game wasn't so great imho, but you might like it. I think it's a bit of a raiden type game, or at least tries to be.. not manic at all. Got some nice story bits :O)
Demon Star (Windows. Apparently the sequel to Raptor, from the same developers Mountain King. It's really not anywhere near as good though... Raiden clone)
Raiden I/II (Ports of the arcade games... which is good because mame can't run them... I think you can get these off of HOTU, fyi...)
Kiloblaster (DOS, same developers as Overkill, but if I recall it had much nicer graphics and stuff... shit these games are old man, I kinda miss em...)
Solar Winds (DOS, another EPIC MEGAGAMES title... it's a 360 shooter if your into that... lots of story elements... Quite similar to the newish game Starscape, but I liked Solar Winds better because I think it's prettier and has more depth... just my opinion...)
Starscape (WINDOWS... just mentioned this game above heh... It's basically like Solar Winds but it sucks ass kinda, and it's got 3D stuff... Personally I don't think the 3D was an improvement in this case! Also the story is very much not-interesting)
Fire Fight! (WINDOWS!! another Epic Megagames title, this one was a LOOOOT of fun for me

It's another 360 shooter, and you can even play it on a network with friends

The music is kick ass, when I was on vacation in the USA a couple years ago I got a copy of this game on CD and i actually listened to it in my CD player quite a bit because the tunes are really kick ass

Anyway, it's not really very arcadey, but if you're willing to play Thunderforce with the over head levels, this is pretty similar, just more forgiving health-wise, less forgiving ammo-wise, and much much prettier

it's also got some various mission objectives and the like... give it a shot.. you can get this from HOTU, and also a hacked version with additional levels)
Zone 88 (DOS, when I bought this years ago it didn't work on either of my 486 computers, but apparently it's really good.. go figure. If you can get it work, you should let me know what its like I'd be curious)
ummmm that's pretty much all I can come up with off the top of my head... guess that's not that many. There are so many old DOS shooters but they really didn't stand out enough and it was really hard to tell them from one another... maybe i'll go through my backup CDRs some time and list a bunch of other ones that probably aren't even worth mentioning
