If you're a fan of Zx-81's work, then you've probably heard of Zx-81's Amstrad CPC emulator, PSPCAP32. Well, Zx-81 recently upgraded PSPCAP32 v1.3.3 to PSPCAP32 v1.3.4, and it's got a slew of new features for users to try.

Here's the changelog for the emulator:

Main modifications :

* Z-80 part as been rewritten using several hints such as explicit jump tables for instructions decode
* CRT and sound part has been optimized

Additional modifications:

* Many optimizations to speed up the emulation, frame rate is now 49 fps at 222Mhz in ultra mode, on CPC startup window.
* Auto-fire mode, press RTrigger+X to switch it on/off (useful for games such as defend or die !)
* Add new hotkeys to setup auto fire speed
* Bug fix in the low battery watchdog
* RTrigger/LTrigger keys can be used in the keyboard settings menu to navigate between Normal, LTrigger and RTrigger compose mapping.
* New "Command" feature in the emulator menu:
o You have now to choose the command you want to run using arrows.
* Default Hotkeys can now be set in the keyboard mapping menu (useful to add hotkeys on existing/previous keyboard files)
* Remove dead code (such as printer, breakpoint, trace support etc ...)
* Bug fix such as : while saving state using hotkey in ultra-mode, thumb image wasn't properly saved
