I can get the U1M setup menu (reset+help) to come up once, and then it will not come back again. I'm really sorry to bother you guys again with my stupid Altirra U1M questions Fortunately, flashing only the 16K being changed takes seconds.
ULTIMA III ALTIRRA FULL
I'm currently working on a small part of the Ultimate 1MB ROM, and the definition of tedious (IMO) would be doing a full 512KB reflash every time I wanted to test 16KB of code on real hardware. The SDX ROM image is a large file (256KB), so it almost feels like you're reflashing the whole chip (although you're only flashing half of it), but BASIC and Operating Systems ROMs and the like are small and are programmed in a matter of seconds, and it makes absolutely no sense to reflash 512KB of ROM when you're only altering 8 or 16KB. Whether it's faster or not, the point is that you don't have to reflash the entire Ultimate 1MB ROM when changing only a part of it. Obviously in terms of the real hardware you would have to reflash each time. To have to re-flash after each one is somewhat tedious, although uFlash is certainly faster than the *.ATR SDX flasher. If there were a problem with "The ROM Generator" and the SDX image, I think I would have seen it by now since it was heavily used. So I'll try again and report back as I said.
ULTIMA III ALTIRRA SOFTWARE
Given the quality of DLT's software in general, PEBCAK is looking good for it. The odds that two programs both had such a major failure, but were fine with the other parts of the ROM seems quite unlikely (though entirely possible). That leads me to believe the 256K SDX image somehow got boogered after being modified and saved back, or each GUI program failed at properly placing it within the larger U1MB ROM build. Since I am doing all of this in emulation, using Windows GUI tools would be slicker, but I'm not afraid to go CLI or character cell program if need be.īTW, using those Windows GUI tools worked fine for customizing which BASICs and OS images were loaded in the U1MB flash ROM. But even if UFlasher works out, I would still be interested to know why the Windows utilities failed. If it fails again, I would like to try the UFlasher method.

I think I will give that method a try again, to be sure I didn't miss something and report back. It has been too long for me to remember what all the symptoms might have been, but I do seem to remember Altirra either crashing or perhaps just a lock up. I have also done the same with a different program. I then used "U1MB ROM Builder" to incorporate that ROM into a larger U1MB ROM. After I made my changes, I saved back out to a 256K SDX (only) ROM. I loaded just a 256K ROM of SDX (formulated for Ultimate) into SDX Imager.
