Season's greetings are coming in, courtesy of Zx-81. The developer has just announced the release of his special Christmas homebrew pack. Each pack contains a compilation of the dev's previous works, which ranges from homebrew applications to games, calculators, and emulators. More details await in the full article.

Homebrew developer Zx-81 dropped by our forums to announce the release of the PSP-ZX81 v1.1.0 for the PSP. This version introduces IR keyboard support, compatibility with custom firmware 3.x and the PSP Slim, a new and improved speed limiter function and more. In case you missed our previous coverage on this application, it is an emulator for the Sinclair ZX81 computer running on Unix systems.

The download link and change log can be found in the full article.

 

If you've been checking out a lot of the recent emulator releases, you may have noticed a commonality among them. Gelon's been making icons and backgrounds for the different emulators, such as for the Atari 2600 and the Commodore Plus emulators. Zx-81 talked Gelon into doing something extra special for the emulator fans out there, and so we now can benefit from a downloadable icon pack for those emulators.

Gelon's Icons Pack features icons for the following emulators:

• ColecoVision (PSPColem)
• Thomson-TO7 (PSPThom, the Ultimate Version)
• Sinclair Zx81 (The PSPZX81)
  
• Atari 7800
• Atari 2600.

If you like what you see, or even if you find yourself using these for your personal backgrounds (nostalgia and all that), make sure you give some props to Gelon and Zx-81 for the icons and the emulators themselves. Enjoy!

If there was any doubt in the minds of the people that ZX-81 was the most hard-working homebrew developer, it can be squashed now. Because you see, ZX81 has released updates to three emulators in a span of a few hours! The emulators in question are PSPZX81, Sinclair ZX 81 emulator; PSPXTI, a TI-92 calculator emulator; and PSPX48, an HP48 calculator emulator.

Here's what's new in each of them:

PSPX48 v1.0.6 (HP48 calculator emulator):

• Save state is now done using zlib so ram file size is smaller and as a consequence, it is much faster to save.
• Bug fix (may display strange characters in the emulator menu)

ZX81 says that Hewlett Packard started allowing HP48 BIOSes to be downloaded off the net sometime in 2000. Although they're needed, ZX81 won't be offering them with his package since they're not GPL licensed.

PSPXTI v1.0.8 (TI-92 Calculator emulator):

• Save state is now done using zlib so ram file size is smaller and as a consequence, it is much faster to save.
• Bug fix (may display strange characters in the emulator menu)

In the case of this emulator, you need to own a real TI92 calculator if you want to download its BIOS. Two versions are included, one for FW 1.5 and one for 2.XX.

PSPZX81 v1.0.2 (Sinclair ZX 81 emulator):

• Add speed limiter option
• Add background change color option
• Add .81 as a valid program file extension

Manuals or documentation for the ZX 81 can be downloaded from here.

As always, all three of these emulators have been released under the GPL license, so the source code is bundled. Below are the download links for all three of them.

zx-81, the emulation machine, has released the Sinclair ZX81 emulator. This version (1.0.1) shows the fact that he has been able to modify and compile the source code of XZ81 v2.1, a Sinclair emulator for Unix and similar operating systems.

It works on FW 1.5 and 2.1+. The ZX81 Sinclair was said to be the third of Sir Clive Sinclair's commercially available computers.  Sir was one of the UK's great inventors with calculators, LED watches and personal home computers, in his long list on inventions. In the home computers category, his first creation was the Cambridge MK14 microcomputer.

Going back to the emulator, the source code has been released under the GNU/GPL license. ZX81 would like to thank all the PSPSDK developers and also Fanjita and Ditlew for the great eLoaders. As always, a readme file is in the download, be sure to check it out.
