  • Overwrite confirmation dialog added to snapshot save and SAVE command.

  • New screen centering system for CRT 15Khz 50hz modes: use CRTL F5-F8 or CS+SS Z,X,C,V in ZX Keyboard.

Changes:

  • Z80 Core: Add accurate emulation of WZ according to the latest discoveries as described in https://spectrumcomputing.co.uk/forums/viewtopic.php?t=10555 Thanks to @redcode !

Flashing tutorial (in Spanish, auto translation supported)

Windows:

Use Flash download tools from Espressif to flash it into your board:

Open the ESP32 Flash Download Tool.
Select "ESP32" as chipType.
Select "Develop" as workMode.

Once started:

Select COM Port (whichever one your board has taken).
Select Baud rate (460800 works fine for me).

Finally:

Load .bin file, set 0x0 as address, check it and press START.
Wait until status panel shows "FINISH", power off and power on your board and ENJOY!

Linux / Mac / Windows:

Use esptool.py from Espressif to flash it into your board:

esptool.py -p USB SERIAL DEVICE -b 460800 --before default_reset --after hard_reset --chip esp32 write_flash --flash_mode dio --flash_size detect --flash_freq 40m 0x0 ESPectrum1.0rc3.bin

(Don't forget to change USB SERIAL DEVICE on -p parameter to reflect the serial port where your system has detected your board)
