**zx-81** · April 13th, 2006, 23:42

Hi all,

Here is a new release of the HP48 calculator emulator for PSP.

What's new in version 1.0.4 :

- Load external application or game files and libraries !!! (with .48 and .lib file extentions).

- Hardware reset of the HP48 (inside the application file selector window)

- Add usefull informations in the README file, and in particular all steps to load application or game files (so please read it

)

The HP48 documentation is there : user guide

As far as i know Helwet Packard graciously began allowing HP48 bios to be downloaded in 2000
(you need it, but it is NOT part of my PSPX48 package because it's not GNU !).

This rom can easily be found here : hpcalc

As always, the package is under GPL Copyright and sources are included.

Enjoy,

Zx.

edit: using the pspx48-mem-slots.zip file, you can add two memory slots of 128k to your HP48

Nice work again! Just tried loading a program and it worked perfect!

I noticed the emu shows 128K of memory, like on my real 48G+ !
In fact, it seems to emulate a 48G+ as it has 128K of memory and only port 0 is available.

Does the emulator code allow for activating additional memory on ports 1 or 2 ?

Thanks again for your hard work!

Yes, you can add two more slots of memory

Unzip the following archive in your psp/game directory.

It contains two files port1 and port2 representing two memory slots for the HP48 emulator

You can now store your .lib files using 1->STO or 2->STO (instead of only 0->STO).

zx-81 you continue to amaze!

The ports work perfect, now the PSP acts just like a HP48GX, complete with both slots filled of ram!

Great stuff, the 48GX's sell on ebay for $300 US and thats without ram cards.
