For fun, I dug out my old Toshiba Laptop with a 32 bit processor to see how mame would do a full compile with Ubuntu 16.04 LTS.

Genuine Intel® CPU U2500 @ 1.20GHz × 2
32 bit
2.0 GiB
Ubuntu 16.04 LTS
compiling mame191

I fell asleep waiting and the computer went to sleep due to inactivity, but it said about 5 hours of elapsed time. I would guess somewhere around 3 hours since 21997 cpu seconds/ 2 cores/ 3600 seconds per hour = 3.05 hours.

Code

/usr/bin/time make -j3
GCC 5.4.0 detected
...
Compiling src/mame/mame.cpp...
Compiling generated/version.cpp...

34653 driver(s) found

My cool discovery of the day is the -verbose option where it will tell you all about the compiler settings used to build mame.

Code

Ok, if I make any change to luaengine.cpp (even just typing a space character) or enabling SOL_CHECK_ARGUMENTS for example:

Code

#define SOL_CHECK_ARGUMENTS
#include "sol2/sol.hpp"

Let's see how long it takes to re-compile and link,

Code

time make -j5

Genius idea, I'll emulate it in MAME soon

If it helps, I came across a manual for the VDP-1000. http://quick09.tistory.com/attachment/cfile9.uf@245A6F405957414B121465.pdf and he's got some posts on his website: http://quick09.tistory.com/category/%E2%97%86%20My%20Z80%20Card The fusion of Apple and MSX. I wonder why MS never did an add-in MSX card for the apple II. Ian Kim's also got an ApMSX card that he's working on. And check this prototype out: A dual ti9929 video card! http://a2central.com/category/its-a-hack/ http://a2central.com/7211/another-p...ice-monupet-ti-d-vdp9929a-graphics-card/
