I have BF2 wired to a solder jumper on my interposer and currently I configured it at HIGH (VCC3). This is correct for higher multipliers 4x and above, not? Multipliers switching mechanism for Mobile Pentium MMX BF0/1/2: 243571-002.pdf page 17 and 18. BF1 uses a different wiring compared to BF0/2. …

I decided to work closely on restoring the original behavior in 1oom, combining it with the fixes from my fork. In order not to interfere with people testing the game, I started posting conservative test releases focusing on overall quality. Latest pre-release: https://github.com/1oom-fork/1oom/ …

just wondering why you don't allow uncovering the map as an option You mean having the whole map uncovered from the beginning? Well, having to unveil the map is a quasi standard gameplay mechanic for this RTS genre. Also, I don't want to change gameplay too much. I could look into adding it as an …

I am getting the messages of course. Appreciate the interest in fixing and improving the adlib driver. But in order to post constructive replies about it, I would have to dive into this adlib driver matter, and more so then I did 9 years ago. Yes I also used Duke Nukem 3D source code as a reference. …

Another noobish question on my part: I've been playing around with different GENMIDI versions from historical Freed∞m releases, and also learned of the DMXOPL project. However, loading the various versions of GENMIDI does not seem to affect the sound of OPL3 music in MBF 2.04. Am I to understand …

Maybe you can find some board photos where the PLL is identifiable. I tried, but either the pictures are not sharp, or the chip is obscured by an AGP bracket or card. I do see brand logo "ICS".

One other thing I have recently changed is how Allegro MIDI code handles pan. By default it would put the channels around listener, which in principle creates a nice "sound stage" effect if you are there to listen to the tunes. In case of OPL3 handles stereo sound, however, this sounds a bit too …
