Thanks Ginza for relaying the good news!

Today i've compiled MAME 207 from the source tarball and tried if:

- my three raw disk dumps from the SCSI2SD for IRIX 5.3 , 6.2 or 6.5 would work.
- i could get IRIX 6.2 installed on a clean CHD (Compressed Hard Disk).

Compiling is not that hard. Just get the dependencies (ubuntu/debian) installed like libsdl2-dev libsdl2-ttf-dev qt5-default and do:

Code:

make SOURCES=src/mame/drivers/indy_indigo2.cpp REGENIE=1 TOOLS=1 DEBUG=0 OPTIMISE=3

With the three images i had varying succes. 5.3 would boot and let me login onto the desktop, but no GL output from programs like gr_osview. 6.5 would not complete boot at all complaining about duplicate TLB's since i have made my images with an R5000@150MHz and a Newport XL8 while the emulator runs with an R4000 at 150MHz and uses the Newport XL24 as gfx. Apparently the CPU spec changed during the MAME development. I was sure the ip225015 is an R5000PC at 150 MHz...

So i decided to go for the IRIX 6.2 install route: Because IRIX 5.3 is relatively easy with only one CD required i was wondering if 6.2 would work. Since you can only specify one CDROM for now i first installed 6.2A from the PROM, booted, got a minimal shell, mounted the 6.2B disk, ran inst, did "keep * ; install default ; go" and rebooted:



This is a screenshot from my Ubuntu workstation with an instance of the ip225015 in MAME running IRIX 6.2. The speed is low, about 20-25% of the native indy clockspeed.
There are some driver alarms from the NG1 (Newport Graphics) about pixel DMA timeouts and bad addresses for the DMA transfer, but it actually works, even the GL programs like buttonfly and gr_osview. I haven't tried networking or serial connection (hello Challenge S) but running IRIX 6.2 on an emulated Indy alone is an incredible achievement and a big hats-off for Ryan Holtz and R Belmont and many others working on the MAME code for such a long time.

I now have to find a R4K@150MHz and redo IRIX 6.5 installation on an SCSI2SD so i can make a CHD out of it, which i can use for the emulated Indy.
