No need to make system a variable, since it's not changed.

It is more a DRY approach. I don't like to maintain the same information on n locations. But I can remove it or set at least readonly. What is expected the "RetroPie-way"?

Leave it as-is then. A variable is used if the emulator supports multiple systems, but it's not the case here and I'd like that intellivision is explicit for both addSystem and addEmulator.

Ok. I have put it as it was before the PR.

if you have shifted the input params why just do something like options+=("$@")

The jzintv options are "space-free", while the ROM (last parameter) could contain spaces. The last parameter should be quoted to avoid shell interpretation.

I don't see how that wouldn't work with my line above - please can you give an example ?

I condensed it. Didn't notice the quotes in your suggestion initially.

I'm not sure I like the converting of all the files to LF to apply the patch. Seems overkill. Also do you mean the patches has LF only not CR ?

Well, yes. LF (0x0a) was ment.
Some other options I considered here: Change the source zip archive to LF (hosted at your site, must be remembered when a new source archive is deployed), convert patches to CRLF (awkward as RaspiOS uses UNIX style endings), use --ignore-whitespace in applyPatch (may have knock-on effects).

I had no success when changing the patch line endings. patch hinted to use either --ignore-whitespace or --binary.
I changed it to dos2unix and limited the conversion to the source file which will be patched.

You need to declare the variable as local for all platforms not just for the RPI.

I'd like to challenge this. Works also fine when the initial clause is not true.

It may work, but it will mean the variable is used undeclared for non RPI platforms and if the variable had something in it in a parent function that data would be included. So this is not correct.

Ah. Now I understand. Corrected it.

The file is marked as executable and lives on a native linux fs so you don't need to use "bash" to run it now.

Right. Leftover from a sample scriptmodule I peeked on unreflected (dosbox.sh).

That's because the script in dosbox is included in $romdir which may be on a fat32 fs so this is needed in that case. As the script is moved now it's not needed here.

If using my example above this would need to be \${options[@]} btw - Unless I'm missing something this should work ok.

see above / intiial comment.

I have made some comments but I'm not sold on including this as it is currently due to the size, and what seems to be unnecessary complexity with the launch script etc.

BTW we don't use flip anywhere else. dos2unix is used though so that would be a preference. But you can probably just use sed/tr though to change the files that are needed (or include the patch with CRLF line endings and avoid having to change the source).

Using dos2unix now. See above.

I guess the launcher size has been reduced already by this review.
A word why I did not patch everything in the source: It would take away the user's option to set a custom resolution and once the border (-b switch in jzintv) function works in jzintv's SDL2 implementation the hard-wiring of a strict maximum (=screen filling) 4:3 jzintv dsiplay may be too limiting.

Flipped the content of the patch files as the filename was not reflecting the patch content.

Are you sure you want to change the base?
