So I tried downloading Masiro's gun mod for RvS - you'll need virtual pc to unpack the .exe file - but it doesn't work, alas, on my setup. It seems to crash the game as soon as it's activated. If I remove the custom .u file from the system folder in the mod, the background graphics appear properly and I can play he game as normal - but without the new guns, which sort of defeats the purpose.
Anyway, I just thought I'd pass on the news in case any of our more experienced modding specialists (Rev?) might have a look at it.
Download for it is at:
