I decided to emulate the //e because I found it the most powerful from the II series without going overboard as I felt the IIgs did. To me, the //e is the top-notch model of the ][ series.
Being a native emulator it means that no operating system is running in the background, so it boots as fast as the original hardware. It currently emulates the CPU with the same number of cycles per line and total per frame, keyboard input is currently done via uart, speaker works, video supports paging and modes text+HGR and HGR2.
As I demonstrate in the video below, it's having some issues and I was hoping maybe you could help me out.
Youtube video (Video tag didn't work)
1) It does not try to boot from floppy when powered on
I quite frankly don't know why. The good ol' ][ did by jumping to address $c600, but my emulated //e just drops directly to BASIC. Can someone here please shed some light on the //e's boot process for me?
2) In HGR mode, HLINE x1,y1 TO x2,y2 does not work
Is this an error in my emulation, or am I using the instruction wrong? I suspect a CPU flag might be wrongly set somewhere in the HLINE function. If nobody knows, I'm assuming it's my fault. But I thought it'd be worth a try to ask here, in case it saves me from hours of debugging and disassembly.
3) Probably related to #1, pr#6 results in an odd crash. The error message is not generated by me, but by the //e's kernel. I *think* it (and #1) could be related to improper bank switching, but either way I need some pointers to get started.
Any input would be more than welcome.
