Hello! I have a real Indy R4400 200MHZ 32MB RAM 1GB HD, with IRIX 6.5.22 inadequate for my hardware (few memory and free 200 MB HD) 

 but run fast and cool. I planning to migrate to irix 6.2.

I must interesting in colaborate to the development of the mame.

I have experience in C/assembly programming since 1990, and in UNIX environment using Indy since 1996.

Actualy compiling the mame in a quad core Q6600 using -j5, and in a i9 9900K using j9 or j17 ( the processor have 8 cores / 16 threads, dont 

tested). 

Using msys64, I not find the option to redirect the compiled files to another directory, and the compiled files stay mixed with the sources, 

dont have a clean install option?

Mame version (mame0210b_64bit).

Compiler command:
make -j5 SOURCES=src/mame/drivers/indy_indigo2.cpp REGENIE=1 TOOLS=1 OPTIMIZE=3 ARCHOPTS_C=-march=native ARCHOPTS_CXX=-march=native

Mame runs in a quad core by 9% (2.4Ghz core). -> using my compiled version.
In a i9 runs a 30% (5Ghz core). -> original compiled version.

I testing using 5 modes:

1) (indigo2R4400_150_8bit_irix62) mame64 ip244415 -gio_gfx xl8 -harddisk1 .\roms\irix62.chd
2) (indigo2R4400_150_8bit_irix53) mame64 ip244415 -gio_gfx xl8 -harddisk1 .\roms\irix53.chd
3) (indyR4600_133_8bit_irix53) mame64 ip224613 -gio_gfx xl8 -harddisk1 .\roms\irix53.chd
4) (indyR4600_133_8bit_irix62) mame64 ip224613 -gio_gfx xl8 -harddisk1 .\roms\irix62.chd
5) (indyR5000_150_8bit_irix62) mame64 ip225015 -gio_gfx xl8 -harddisk1 .\roms\irix62.chd

Interesting detail:
-Using original compiled mame downloaded from mame website,
(in q6600 PC) all virtual machines works correct.
(in i9 PC) the only hardware emulation ok is indigo2,
others virtual machines scroll 1/2 screen down, impossibiliting the visualization of the low portion.
-Using my compiled version,
(in q6600 PC) all virtual machines work correct.
(in i9 PC) dont tested.
-All virtual machines dont have audio.

Creating the virtual disk image (chd) using the mame commands, dont work in emulator, only the full disk image irix62.chd, and reusing this 

to install irix 5.3 over.


How to change the MAC address (eaddr) in Indygo2? the setenv -f eaddr 08:00:69:12:34:56 dont work. Only in Indy this works.


Curiosity: My Indy have the "CMOS" working since 1996 (manufactured in 1995), the battery into the chip is long life? My PCs have to 

change the battery by 3 to 3 years.
