MESS Git (2015/06/22) is compiled. MESS(Multi Emulator Super System) is an open source emulator which emulates a large variety of different systems. MESS is a source-available project which documents the hardware for a wide variety of (mostly vintage) computers, video game consoles, and calculators through software emulation, as MAME does for arcade games. As a nice side effect to this documentation, MESS allows software and games for these hardware platforms to be run on modern PCs.

MESS Git Changelog:
* Left a comment in AY8910.c about io ports A and B. (nw)
The io ports are designed as open collector outputs. Bits 7 and 8 of
AY_ENABLE only enable (low) or disable (high) the pull up resistors.
The YM2149 datasheet specifies those pull up resistors as 60k to 600k
(min / max). We do need a callback for those two flags. Kid Niki (Irem
m62) is one such case were it makes a difference in comparison to a
standard TTL output.
* just some whitespace cleanup, no functional change
* Analog drums and filtering for Kid Niki et al. [Andrew Gardner,
Couriersud]
In addition:
- Generalized the device family concept.
- Truthtable device can now define their own device family model.
* small cleanup
