Disclaimer, I own the steam version, I installed the "Unofficial Max Pack 95 Restoration Project Pack " and I see the installation folder but I see many different exes CAR95H1, CAR95H1G, CAR95H2, CAR95H2G, CAR95, CAR95G.

Can anyone direct me to which exe I should be using, it maybe because im tired but I didnt see mention of them in the exe, any other th8ings I should do to the game as well to make it work properly?

Gotcha, is there any way to make the menu/videos/cockpit view full screen? They are tucked into the corner of my screen at a super low resolution

HDTest is unofficial modification. It fix in game resolution to HD, but graphics stay the same as for hires (in game) and lores (in menu - not scaled), so it appear small in corner. In theory we can re-size all graphics and replace existing graphics in game, but in practice (I have tested this already) game behave strange and crash. This happened probably because of bug in memory handling in game. So this need to be fixed first and implement proper rescale for selected resolution. AFAIK currently no one work on this. There was topic about this on carmageddon.com, but the site is closed.

Another method is to re-size whole screen running game in hires, but this doesn't give a real HD in game (just re-sized 640x480), so in my opinion, better is to run hires (or HDTest) on full screen without resizing, than re-size hires.
