CoolingSmartManWayDay, haven't you already been warned about posting links? Please don't do that like that.

It's not top-down, but perhaps some port of RoadBlasters?

Perhaps Rygar? Which appeared on the PS2 around then, and years later got a Wii port.

Yoshi's Cookie? Tetris Attack?

Probably Bonk's Adventure

Microbot, or maybe Nucleus.

Fixed that for you.

I also did Google up "Prism land sunbathing furry boss". That was interesting, I've never seen this brickbreaker before. Dat bullet hell powerup...

Probably Adventure Island? There were a few of them.

Throwing out a random guess mostly based off black draw-in. Crime Killer?

Perhaps Style Savvy?
If not that, do you have a guess what system you would've been playing on?

Toggling between black and white makes me think Ikaruga, but that's not a platformer. I found a list of 'games like' it though, so maybe it'll pop up there?...

You're thinking of Eternal Champions. The dude in a trench coat was Larcen.

That'd probably be Hot Slots. Not a lot of porn NES games.

The first thing that pops into my head is Cybernator. I think there were 2-3 other mech type games, like Metal Warriors and stuff.

I think Metamorphic Force?

I have no idea what you're looking for, but I have a tiny suggestion. Almost every PS1 that came out back in the day shipped with an 'Interactive CD Sampler' demo that contained an assortment of...

No idea. But you could provide more details that might narrow down the possibilities. Like when did you see this game, 2 weeks ago, or 10 years? What sort of system could it have been running on?...
