Derby++: a new Spectrum firmware...

...for your esxDOS, TurboSound, and ZXHD equipped Spectrum +2A.

https://zx.itch.io/derbyplusplus

Brief overview:

* Full esxDOS support in all modes (esxDOS 0.8.6 requires Dr Slump's NMI menu).
* Recompiled version of the Spanish 128 BASIC editor with all the usual extra features plus:
* ULAplus support (default palette and PALETTE command).
* 6 channel PLAY command.
* 100% compatible 48 mode (uses the original ROM, locks paging)
* Built-in diagnostic ROM (works with divMMC/divIDE enabled)

[update] I've added TR-DOS to the boot menu.

Derby++

A replacement firmware for 128K Spectrums based on version 1.4 of the Derby development ROM.

The Spectrum 128 was a Spanish machine commissioned by Investronica and launched in 1985. It shipped with a keypad that provided additional editing keys. The UK version got a simplified ROM and no keypad. Derby++ is an enhanced version of the ROM that shipped with the Spanish machine. It has the following features:

All modes work with esxDOS on divIDE and divMMC.
48 mode ROM is 100% compatible with the original ROM (because it is the original ROM).
Holding down ENTER while selecting 128 BASIC is equivalent to Tape Loader (if used in a 32K ROM configuration hold down ENTER on power on or reset).
In a 32K ROM configuration, hold down BREAK on power on or reset to boot into 48 mode.
When CAPS LOCK is off, lower case text is tokenized.
When CAPS LOCK is on, SHIFT produces lower case text.
Will run software compiled with HiSoft BASIC 128 (although not the editor itself).
New mapping of extra editing keys.
Fully bug-fixed and optimized editor and BASIC.
Variables are persistent (not CLEARed when a program is RUN) in 128 BASIC.
The SPECTRUM command is replaced with the PALETTE command for ULAplus.
Default 16 color palette.
PLAY command supports six channel AY (TurboSound).

It has the following features in common with the Spanish 128:

Full-screen string editor.
Running calculator (use from BASIC as if you were in the calculator option on the UK machine).
Five new direct commands.
PLAY command.
Use keywords as variables by entering them in lower or mixed case (when CAPS LOCK is on).
Use embedded control codes.
Set the INK and PAPER colors of the editor.
Much faster editor than the UK machine.
