Greg,

Yes, the first load of VB81 can hang with this error!
:oops:
It seem to be a "loop" error to prepare the Vb workspace system.
I had to reload it.
May be the anti-virus protection who add a launch latences on OCX, DLLs…
On W10, this bug was trapped with a system update.

Windows add a launch screen how avoid this error!

I worked on a new release, enclose the Centronics emulation and some corrections.

VB81 XuR: "07-09-19"
[edit: update available]

Place new ROMs in the ROMs directory.
Memotech SIF and CIF not connected.
Centronics seen working.
"Save binary" using a REM line: ok.
The timer overclocking is back, but can hang the keyboard typing (use it to print/calculate…) and you had to reset it to enter something on the keyboard.
Some other bugs fixed too…

… must update the ini file before crashing
:?:

No "ini" file in the Xur !

It store configs in the windows register datas.
#1 Launch = "object error"
#2 Launch = "Ok."

Re: [Vb81] SCR load bug

Post by GCHarder » Mon Sep 09, 2019 11:06 pm

When loading back a saved SCR file it will ovewrite the beginning of the VARS area. This is because the saved XXXX.scr file is 793 bytes when it should be 792 bytes. This is not a new bug it's been around for awhile, I just thought I'd mention it. It can cause problems at times.

Regards;

Greg

Great job Greg !

Another (hidden) bug fixed.
[Note: This function can't be use on an unexpended D_File screen! The ZX81 will hang or reboot… i tried it!]

The new BIN/SCR D_File loader can now load old, and new saved files!

Working on the Memotech SIF card…

All the best.

Hi,

Another update to load the Memotech Memotext ROM... if it's available.
The Memotech CIF isn't link yet, the BIOS jump wasn't dumped.(this tread)

...or...Test the Memotech Centronics card alone and dump only 3 PEEKs:
10 PRINT PEEK(2169)
20 PRINT PEEK(2170)
20 PRINT PEEK(2171)


Update 12/9/19:
