I can't get this to work using the image loader of MyIDE-II. The title screen shows but nothing works. Sijmen, do you know how to run this?

Ok, not good, this is a strange program....

It uses OSRAM (C000-FFFF), and runs without NMI or IRQ.

So MyBIOS-RAM/F2 is killed during load.

I tried the (new development) MyBIOS-ROM, it loads and works until you need to flip a disk.
Without NMI/IRQ there is no way to intercept hotkeys and perform a flip.

The hotkeys are lost, so no way you can flip any disk.

This means, you need to load this program from disk-drive (or emulated like SIO2PC/SIO2SD etc)

Grtz,
Sijmen.

Thanks for trying Sijmen. It works with SDrive-ARM but I was hoping to get it working with MyIDE-II since it is my primary boot device.

Hi Rich,

Short update, I managed to make it work on the work-in-progress MyIDE-ONLY.ROM #4
This version in not uploaded (yet).

Like I said before, This is a strange program.
It runs totally without IRQ or NMI.

Since the IO-patch works (I can load the disk using CF-access) and the Atari Planetarium comes up:
I added a small check before performing the actual IO.
That is, check if the key pressed (that asks for you to flip the disk) is a valid "number"-hotkey.
If true, do the hotkey-function first, then do patched-IO
and..... tada..... that works !
yeay, 1-0 for me.

Send me a p.m. if you want a this w.i.p.-myideonly

Grtz,
Sijmen.

Version #4 uploaded.

The Atari Planetarium works.
Press SHIFT+CONTROL+2 when asked to "Turn diskette over and press a key".

Not sure if this will ever happen (I did not encounter this yet):
When asked to insert side A, press SHIFT+CONTROL+1

Enjoy,
Sijmen.
