[RELEASE] PSPCAP32: Amstrad CPC Emulator for PSP v1.0.3

[zx-81]

Hi All,

Here is a new version of PSPCAP32 the CPC Emulator for PSP.

What's new in version 1.0.3 :

- Full Speed Emulation, due to several optimizations :
> Z80 emulation code (rewrite instructions decoder part)
> Display/graphic functions improvements

- Add a "frame skip" option in the emulator menu


What's new in version 1.0.2 :

- Emulator options menu to change parameter such as sound, clock ...
- Zip archive (.zip) support for both disk files (.dsk) and snapshot files (.sna).
- User Keyboard mapping file to specify dedicated mapping between CPC
and PSP keys (usefull for games that use specials keys and/or don't support joystick).


How to use it ?

Have a look to the README.txt file !

Two binary versions (for 2.x and 1.5 FW) and sources are included in the zip archive.

This package is under GPL Copyright, read COPYING file for more information about it.

Enjoy, :)

Zx.

Nice work, glad to see zip support.

yeah every emulator should have zip support to save memory

Right ! on our case, a disk file is 200k and a snapshot is 128k ... after zip the size is generally divided by 10 ! :icon_bigg

Yes. it was not so easy to integrate, because the original C code of Caprice32 (that support zip files) wasn't portable at all. It was mainly due to byte/word alignment problems : on a mips r4000 word memory access must be aligned on a 4 bytes address, and this is not the case for x86 processors.

Is it just me, or does changing the clock speed have no effect?

I'm running on 2.6 firmware, Japanese white machine, and no matter what settings I use (including fiddling with the clock speed on the e-loader itself) it always seems exactly the same.

Still, great to see quick progress being made.

Clock change has no effect even for me on 2.5. I think the code i use should be taken into account only with 1.x FW (kernel access).

Great emulator.

Your on a roll Zx-81! Keep up the good work!

hi,first thanx for this emulator
i really like (gryzor,ikari,ghost goblins,solomon's key , ah the good old time)
the clock has not effect at all even on 1.5

[zx-81]

ok thanks for your feedback :). May be i've missed something on the usage of the function to call to modify clock speed. Anyway i will release a new version very soon, and few minutes ago, i succeed to have a working emulator at 100% original CPU original speed !

[darksun48]

wow it's really an good news :)
i'm impatient to play with it

thanx
i'm trying right now :icon_smil

It doesn't seem quite full speed on a 2.6, but it's close. The sound is still slow, and needs turned off to maintain a playable speed. Changing the clock speed still has no effect but I gather you haven't tweaked that code?

The frequency of these updates is certainly something to praise. Each release getting better and better.

I must remember to have a running clock in my bathroom. "ETA to Batman on Bog" written above it.
