No.17982 Robbbert Senior Tester Sep 18, 2020, 12:11	These machines are marked as NOT WORKING. sun4_60 doesn't even have a screen by default.
No.17983 Tafoid Administrator Sep 18, 2020, 15:01	Correct. This machine (and in fact all the SUN machine drivers) are not at state where anything can be guaranteed to work in all instances. This is the reason they are flagged as MACHINE_NOT_WORKING in driver and you should get a message on a RED screen when you start up your emulation attempt stating this. As a policy set down long ago from MAME's Developers that in most instances such flagged machines are not subject to accepting bug reports - this is the case here. I would contact the people who made the claims of things working and see if there is a previous version they can name/attest to booting and use that. Closing.

Correct.

This machine (and in fact all the SUN machine drivers) are not at state where anything can be guaranteed to work in all instances. This is the reason they are flagged as MACHINE_NOT_WORKING in driver and you should get a message on a RED screen when you start up your emulation attempt stating this.

Closing.
