Don't know what to tell you. The videos are from a real ZX81 (Timex Sinclair 1000 and ZXPand+). I just fed the data to Andy's player, didn't adjust any AY values. It could be the cheap camera, which was recording at 10FPS. Could also be a PAL vs NTSC thing.

ZXPand Organizer
Hi All; ZXPand Organizer is a program that allows a ZX-81 with ZXPand or ZXPand+ interface to create a "project" of related files. It is a way of organizing files on the SD card, or emulator that supports the ZXPand. It is very similar, in some ways, to an old style MS-DOS frontend. See the enclosed...

Re: [Vb81] Disassembler Bugs
When looking at a disassembled listing forward jumps are always off by one, they don't match the opcodes. For example, 20;01 is listed as JR +2 instead of JR +1, this can be confusing if you don't remember that. On the other hand backward jumps are listed correctly. Bitwise manipulations involving I...

Re: [Vb81] SCR load bug
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.

Re: [Vb81] Bug Report Error 91
This is more of an annoyance than a bug. It occurs when loading the program and a folder is not found. It prints the message then crashes out. Then reloading it works, must update the ini file before crashing.

Re: [Vb81] Test release. Bug Report
This is a weird bug, see the attached picture. Almost seems like it's corrupting the ROM image somehow.

Re: Crippled Software
This is a problem with ZXPand not the program. When generating standard ZX81 type characters SHREB expects to find the character patterns at $1E00, which are are no longer there because of the ZXPand overlay ROM. Pseudo-hi-res programs also have a similar problem. Try loading the program with the /x...

Re: Crippled Software
Horizontal coords are based on byte positions while vertical coords are based on pixel rows. The max horizontal pixel coord is 255.
