yeah YAARTTT will error at 0x02000000.
Saying that.. It might not bus error on TTram..
Those two statements seem contradictory.

YAARTTT will error as the data is wrong (Assume regardless of BERR). If EMUTOS is only checking for bus error then it would find all the RAM.
EDIT:
I've not looked at EMUTOS code, but probably its detection and isolation of "bad RAM" needs a bit of work. It would probably make a good feature and it's how TOS works as well.

*Aah* sorry -- I was talking about bus errors so assumed you were too when you said YAARTTT will error at 2000000.
Yes, the bus error's needed for EmuTOS detection unless you compile a hard-coded version. My point was if you don't get a bus error accessing 0x2000000 then the RAM detect will fail.
Want a PRG version with 16MB AltRAM hard set?

Ah cool thanks @Badwolf not at home until tomorrow night now :( do you know if altram can be disabled totally? As the fastram.prg installs it anyway, probably won't play nice with emutos anyway :roll:

Yes. Needs a special build to disable it on the ROM version, but the stock PRG version (not the prior one) won't install it if TOS hasn't already.
Let me know if you want an image.

Holy heck.. EMUTOS is fast on a 030! I swear the floppy is going faster as well...

Compared to a STE (with blitter) its actually beating a physical blitter in those tests!

Hehe, good job :D
Indeed, that's fast.
As you see, a hacked EmuTOS is ideal to run on a hacked hardware.

I keep telling people to use EmuTOS but they want the nicer icons of 2.06. :) Which i asked you to put in EmuTOS like back in 2012 :P
