New release of EightyOne available

[Moggy]

I know I'm thick regarding these things Charlie , but would say looking at the AY code in an emulator like SZ-81 give any clues on how to rectify EO or perhaps drop the AY in EO altogether for what use it is?

[sirmorris]

More likely the second option. I have looked at various source code and from what I can gather there is little similarity.

Understood Charlie obviously not a standard "bolt on" module type thing then .

i needed to create 2 new files by copying zx81-zxpand.rom twice

and renaming each to...

zx81edition1-zxpand.rom
zx81edition2-zxpand.rom

It's ... it's too hard

The AY emulation is broken beyond repair I fear. I've looked but it's not immediately obvious what's going on.

would i be right in saying that the relavent files are :-

sound.h
sound.c
dxsound.h
dxsound.c

i might have a looksie and see if i can get my head around whats going on....

That would be appreciated andy. I think those are the files to look at, yes.

We're looking at either a new release with updated ROMs or maybe updated ROM detection logic.

EightyOne version 1.4 is now available from here

It resolves the issue of not finding zx81-zxpand.rom when using the ZXpand functionality. A few other tweaks and fixes have been made but no changes to the AY code (the aim of this release was just to resolve new issues identified in the 1.3). Note that folder names have changed and so it is best to completely replace any previous installation.

Just an observation.

If I load an ordinary Basic program then decide I want to edit a line or two then resave as a P file,when I reload the edited file it lists/runs as the original unedited file and yes I give it a different name upon resave.

Any thoughts?

[sirmorris]

So..

LOAD "PROG1"
<edit edit edit>
SAVE "PROG2"
LOAD "PROG2"

.. gives you the content from prog 1??

[Moggy]

Yes!

I use the SAVE TAPE function which I believe saves as a TZX file not a P file as I posted earlier from the drop down menu as opposed to typing SAVE "XYZ" in the emulator screen if that helps.

It's as if the TZX save doesn't carry across the alteration.
