With the actual (Jr-cutdown) version of the V2 emulator mostly everything seem to work (input, output, DIR, sdfiles, sdcopy etc) and I can exit MBASIC with the system command and the emulator says "CPU halted" and reboots (freeing the system-memory/TPA or is reloading the "CCP") - whch seems the right action after leaving MBASIC.

On the other hand when I try to exit Wordstar 4.00 (WS.COM) with the X command the emulation seem to hang/freeze.
This also happens with Wordstar 3.30

I have attached a zipped O:-Drive (o.dsk) with Wordstar 4.00
Maybe could you try in your original compiled Emulation if it will also freeze?
Could this be a mishandled CPU-Instruction? Could you trace this on your side?

Thanks in advance :)

Your Emulator is working fine when using ESP32-Core v1.0.6 - Thanks :)
But when using a newer ESP32-Core v2.x.x the SD-Commands like sdfiles
got problems :(

sdfiles does show the content of the directory (/downloads) but then the ESP32 does disconnect/restart.

Did you ever test a newer ESP32-Core? Or do you got an idea what to change?

While compiling the follwoing warnings/errors are shown:
In function 'bool SDprintDir(fs::FS&)':
.ino:504:1: warning: no return statement in function returning non-void [-Wreturn-type]

I also created a feature cudown version of this emulator to get it to work with a WeMOS D1R32 (normal ESP32) and a Deneyap Mini (ESP32-S2)

The ESP32-S2 does need ESP32-Core 2.x.x because it isnt supported in ESP32-Core v1.0.6

Many thanks for informations & ideas in advance :)

Hi,
maybe you got an idea for me?
I ported the my CutDown/Junior-Version of your emulator to a TTGO VGA32 which does use FabGL-Library-Terminal for VGA-Output.

Now I want to track down some issues:

Input-Problem:
On some circumstances I have to press Enter/Return twice to get it recognized.
The first time after start is after the Emulator displays "Starting Z80".
There I have to press enter to get a prompt.
At the A> prompt when I only press Enter or press Enter after some Spaces it does work.
When I give the DIR command the Cursor does go to the start of the Line after the first time I press Enter (LF?) and after the second time I press Enter (CR?) it starts the command.

Output-Problem:
I could do give the command DIR serveral times (Ok with pressing twice Enter) and the output works fine.
But when I start a BASIC-program with a Mandelbrot/Fractal which should output many lines it stops after some lines and I have to press any key to get further display-output.

If you got an VGA32 or would be so nice to take a look at the source - you will find it at https://github.com/guidol70/RC2014_ESP32_Z80_Emulator_VGA32

[EDIT]
via the Source-Code I rerouted the emulator output to the USB-serial port of the VGA32 and there is no input/output-problem ;)
So I will try to ask the author of FabGL if he has an idea :)
