Hey everyone,

I just posted this in the Discord, but I thought I'd put it here for more exposure. I've been working on a patch to fix the jump jet fuel recharge rate in the DOS version of Mech2 and I'd like to put it out there for testing. All the notes are in there and a download for an .ipf file you can use to patch your MW2.exe as if it were a ROM hack for NES or something.

Patch to Fix Jump Jet Fuel in MechWarrior 2 for DOS

In theory, this will let you run the game in DOSBox with maximum cycles without losing the ability to use jump jets. Patches for NetMech, GBL, and Mercs are pending.

Have fun!

I tried the patch but got a black screen. This is probably because my CD is the DOS-only version (the MW2.EXE CRC doesn't match, not even patching to DOS 1.1).

But I really appreciate the info about the frame-rate command line argument. This worked flawlessly for me in DosBOX with max cycles. Even at 45fps it was way smoother and more enjoyable than manually setting DosBOX cycles (which results in FPS varying a lot depending on the scene). This brings me back to my childhood with my Pentium 200MHz :)

Do you know a way I can start the game normally with the FPS limited to 45, rather than jumping into a specific mission by command line?

Everyone. DO NOT USE THIS at its current state. It only works sometimes and when it doesn't, it needs to be reinstalled. Also lowering DOSbox cycles will no longer fix jets with this enabled. I had to uninstall this completely just to get everything working again.
