This is how it was encoded. The gameport only exposes 8 bits: Joystick X and Y axis (2x) Joystick button A, B (2x) In addition, since Y and Y need more than one bit, the way to read those was to reset a timer and continuously read the port until the bit flips and the time it takes is the measurement …

For some of these caps equivalent electrolytics may be difficult to find anymore, but you can replace those with polymers and use roughly up to half the capacitance of original capacitors (there are not much over 2000uf polymers available). Is there any documentation of how that "roughly up to half …

I have a K8N Neo2 (from 2004 ish?) board here that still POSTs, but has visible problems with the capacitors, so I assume I should replace those soon to avoid frying the board and/or CPU? The capacitors near the CPU are labeled as 1800 uF, 6.3 V - it seems like there are 7 of them and 3 show signs …

If the system it is being run on is x86, then not everything should need to be emulated. This is what the "dynamic" core (dynamic recompilation) does in DOSBox-X, although it seems to be limited to 32-bit x86 . The "modern" system you're running on most likely is x86_64 (aka amd64), which isn't the …
