I think I found a good yellow without going too crazy and it wasn’t too hard to get.

Duimon · 9 June 2022 10:52

Not bad… although I think it leans a bit too much to green.

hgoda90 · 9 June 2022 10:58

Yeah it does I was going to fix that.

hy!!! is it an official console? I don’t remember… what games that company made?

hgoda90 · 9 June 2022 11:07

The Uzebox is a retro-minimalist 8-bit open source game console. It is based on an AVR 8-bit general purpose microcontroller made by Atmel. Check out http://uzebox.org/wiki/Games_and_Demos for the list of games released.

I never heard of this system either.

I installed the Mega Bezel Duimon ADVANCE shaders and they look amazing, if I wanted to add a little more filters or lines to some games… how do I do it or where do I edit? thank

If you are talking about the GDV CRT portion of the shader, they are at the bottom of the parameters list. Just press up when you open the dialog to get to the very end.

If you are talking about something else I need you to be more specific.

I did what you told me but I can’t find that word GDV CRT! it’s like adding scaline, to hide a bit the pixels or edges of nes and snes sega games

Duimon · 10 June 2022 04:14

Yeah it’s lot listed as that, here…

This is after the grade stuff. Everything below this heading is for scanlines etc.

This is only for presets with “Guest” in the name. “LCD-GRID” is different.

Here are some shots of the Sinclair ZX81.

I have yet to find any colored games but even they are monochrome I believe. I think it looks good in amber monochrome mode.

This graphic may be a little premature, the core is not very complete. I haven’t been able to figure out the keyboard mapping and it may be different for each game. The defaults do not work.

If it were a MAME machine I wouldn’t release the graphic, but I will since it is an RA core.

This was a simple but tedious graphic. I plan on doing some more of the simple ones next, in order to get as many done as I can.

According to Wikipedia The ZX81’s built-in RF modulator can output a video picture to either a UHF 625-line colour or monochrome television. So monochrome would most definitely be the best way to go.

From the Libretro Docs on EightyOne core:

Colorization works by loading a program prior to loading the game. This program will check if the 
Chroma 81 expansion is installed, and, if it is, configures the colors of the ZX81 characters, and
then loads the original game, which runs unaware that it's playing with colors.

Since the EightyOne core can't load arbitrary programs from the file system, the colorization 
program and the game must exist in the same file.

Yeah, I just found a link to some color roms. I will try them out and see what I can do for the key mapping. Maybe the guys over at Batocera can help. I think they support this system.

How to set this zoom effect?

hgoda90 · 10 June 2022 07:29

You have to change the [Viewport Zoom] Settings. To get the exact, or at least close to the picture, use the following

[Viewport Zoom]
    Viewport Zoom: 148.60
    Viewport Position X: -3
    Viewport Position Y: -64

Duimon · 10 June 2022 12:05

Actually, my presets are set up to use Non-Integer Scale % to do this. You will probably have to do some Screen Y Position adjustment as you go.

hgoda90 · 10 June 2022 12:22

Forgot about that. You did set it that way to make it easier.

Change to

[CRT Screen Scaling]
    Non-Integer Scale %: 83.80

[Position Offset]
    Position Y: -2.00

ZX81 is in the repo. I still haven’t had any luck getting the keys to work.

I decided against monochrome mode since, in theory, there are color roms available.

It will be there in case the core improves.

BTW. MAME support is not good either. Oh well.

hgoda90 · 11 June 2022 00:46

I was going to create a variation called [B&W] if you didn’t do monochrome so either way. And yes, I have color variations planned out as well.

The keyboard works if Controller 1 is set to none and Controller 2 is set to Sinclair Keyboard. Hotkey Enable also has to be set to a key so the hotkeys aren’t activated. The Shift key on the ZX81 is the Right Shift key on the keyboard.

hgoda90 · 10 June 2022 23:29

If anybody is interested I found a book that has programs that can be written with the ZX81.

Duimon · 11 June 2022 04:51

Here is a WIP on the Tomy Tutor TP-1000.

I just have the characters on the keys and I will be done.

I had to take a few liberties with this one so there was actually something to see. (Everything was hidden behind the bezel. )

This is an interesting system. It is essentially a ZX Spectrum clone, so has some really good games.
