[Feature] Testing and ideas for the new export-roms subcommand

[alucryd]

Hi guys, just merged my initial work on the export-roms subcommand. Right now it supports all the formats convert-roms does, as well as an additional special case for PS2 and OPL, that will convert the PS2 CUE/BIN CD games to ISO as OPL only supports ISOs. I also added a -g flag to only export 1G1R games.

I'm open to ideas as far as formats and filters go, formats can be lossy here so the sky is the limit as long as there's an open-source tool for it, preferably cross-platform.

And as usual, testing is greatly appreciated!

Added support for WBFS via wit. I should probably start making some kind of system whitelist for each formats, that's already 2 new formats that are very system specific.

I’m not sure if you covered this but it would be awesome to be able to specify output directories (or handle this automatically) for certain frontends, for example IGIR has this implementation: “ Specific hardware” on this page: https://igir.io/output/tokens/

I have a similar feature for sort-roms, right now it's in its infancy and can only sort roms in alphabetical subfolders, nothing yet for export-roms though.

That's a neat idea, I can both expand the sort-roms feature and implement it for export-roms. I'll need to document myself on each of these specific frontends.

A really nice feature for the export-roms would be a file option, where the file would have the system and the list of rom games. Like i have 26 PSX games I ripped and currently i just rsync the entire folder to my mister, but it takes a lot of my SDcard (and i like the current export function because it compresses to CHD). I really only need 15 of those games (a lot are demos). Being able to have a file to export/convert the roms (and check the target directory to make sure there are no other files in it (I.E. if the name of the rom changes, it will remove the old one and create the new one or possibly rename the target) would be nice.

This would probably be nice for SDcards for raspberry pi based systems as well (mount the card and export).

@siffland Thanks for the suggestion. I had thought about something similar. The idea was to optionally prompt users for games to export using a select_multiple, and write a state file inside the export directory listing all exported files and their format. Subsequent exports would then compute the delta against this state file, only export the difference, and remove files that are no longer selected. I'll add this to my backlog.
