Retro HQ Lynx Cart Menu 1.4

[GadgetUK]

Now that's a nice idea! Should be relatively easy to do that I think. Maybe I will add that in at some point.

I meant the 'text file' bit listing cheats and codes etc. Save states I don't think will be possible. Might be possible to load them but tricky I think.

I'd still "kill" for a text-viewer option to see level codes etc.

 

Orrrrrr a save-state of certain games would even be just as awesome....imagine playing Chips's Challenge without the hassle of having to enter the level code each time

 

Take the "hacked" version with level skip

WHERE, WHERE, WHERE, WHERE ??? (but even so.....skipping to Level 100+ ?

 

Not that I have reached that yet....

Wow, thought you'd already seen my idea about this

 

I remember seeing those text-only files for about every Lynx game with tips and tricks and level codes way back in the early 2000's or so....downloaded those from internet and printed them out and had them in my Lynx bag then......but it should be "easy" to have an option to show a file like that from the menu....would be brilliant IMHO

 

Maybe you could use the B-button to select the text-file viewer for the selected game and the A-button to load the game ?

Did not find the atariage topic anymore, but the links for the video and script which you have to run on your original rom.

Nice story, sage

Can anyone please tell me step by step how to do proper lsd Preview files for the SD-menu?

I know the size must be 160 x 102 in 16 colors. So I make a screenshot with IrfanView from Handy, resize it to 160 x 102 (cut the edges of) and downgrade it to 16 colors. But the utility always says, that I do not use the right file. Looking at the info with IrfanView, the bmp-file I want to make a lsd-file from and the AvP-Preview-Sample-File are exact the same.

So where do I go wrong? Which program should I use to reduce the colors?

I did my lsd files using Gimp and cc65.

 

From GIMP you choose Image->Indexed

 

Then you choose 16 colours

 

Export the result as image.pcx

 

Open window->palettes

 

Go to the top of the list to find your image's palette. Export as txt file.

 

From the palettes txt file you need to type in the palette to the Lynx format. (I have a file palette.s in the attached source for this.)

 

With the image.pcx and a good palette.s type make and you get image.lsd.

@karri: Thank you very much for your description. I get till "Export as txt file"

Is the palettes.s file always the same? And where do I type "make" and which environment do I need therefore? Sorry, I'm not a programmer :/ Could you please explain that a bit slowly for me? Thank you in advance!

You need to install the cc65 tools as described in the Atari Lynx Programming forum. It can be installed to Windows, Linux, RaspberryPi, Android, Mac. After install you have the tools including "make".

 

The palettes.s is still entered manually. What I do is to export the palette from the image using Gimp->Palettes->export as text.

 

Then I copy the values manually into palette.s.

 

When you export a palette from Gimp it looks like this:

 karri@swing:~$ cat palette.txt 
#2d2633
#362d2d
#764d4f
#525497
#2b6a4c
#b74556
#976839
#ea545c
#58a343
#5a96f1
#e78e61
#6bde5f
#65d1fe
#d2df61
#fccad3
#d3e6f0

The values are RGB #2d2633 means RED 2d GREEN 26 BLUE 33

The Lynx palette is different. The order is GBR. So we want this to become GREEN 2 BLUE 3 RED 2

#2d2633 -> 232
#362d2d -> 223
#764d4f -> 447
#525497 -> 595
#2b6a4c -> 642
#b74556 -> 45b
#976839 -> 639
#ea545c -> 55e
#58a343 -> a45
#5a96f1 -> 9f5
#e78e61 -> 86e
#6bde5f -> d56
#65d1fe -> df6
#d2df61 -> d6d
#fccad3 -> cdf
#d3e6f0 -> efd

The Lynx palette is also in two parts. First we write all GREEN values, the all BLUE/RED values

.byte    >$232
.byte    >$223
...
.byte    <$232
.byte    <$223
...

The Lynx Palette Generator can help with converting colour values.... https://atarigamer.com/pages/atari-lynx-palette-generator

 

Also you should look at the Lynx SD Menu Loader 2... https://atarigamer.com/articles/introducing-lynx-sd-menu-loader-version-2
