Readd the .img selection feature #372

Closed NightScript370 closed 1 year ago

NightScript370 commented 5 years ago

With the release of 7.2.0, we saw the addition of loading up SNES and Mega Drive/Genesis using .img files loaded from sd:\_nds\TWLMenu++\emulators\SNES.img and sd:\_nds\TWLMenu++\emulators\GEN.img. While they involved a bit of work to setup, it had the ability to have roms packed and each .img had a 12/28 MB limit (depending on the console). The release of 7.3.0 saw the addition of having .smc & .gen files being loaded like other roms (with the brand new .img template method). However, there are a few regressions:

Now, the second reason doesn't apply to me, but the first and last one do. Therefore, I'd like to have .img loading implemented back into TWiLightMenu++, but not in the exact way as it was done before. The problem with the way it was done before is that there wasn't really any organization at all; All the ROMS had to go in that one .img file. Therefore, I suggest a new implementation:

Why not have the ability to load any .img file anywhere on the SD card using the actual menu instead of just a button? Then, once that .img file is loaded, it could ask a prompt which emulator it'd like to use and you'd be able to choose. That way, we could have an img file located in the roms folder titled favorites, one titled sonic, one titled mario, and much more. Having this new system would solve all of the problems I have with the regular loading, and there wouldn't be any regressions of re-implementing this feature.

Note that the 3MB limit comes from jEnesisDS, not TWLMenu++. In jEnesisDS, whenever a 3MB ROM tries to be loaded, the emulator rejects it, and returns to the ROM list.

Really? I thought it was just the .img template limit. My bad

@NightYoshi370 is this still relevant?

NightScript370 commented 4 years ago

Well, it hasn't been implemented yet so I suppose so

  • It is no longer compatible with lolsnes

Does/did lolsnes have any advantages over SNEmulDS?

  • A pack of roms loadable out of the box with no extra work required in TWiLightMenu++ aren't possible anymore (well, until .zip loading is added, that is)

What do you mean by this? I'm not sure I understand.

I have reached the following conclusion after rethinking: Why should TWiLight Menu++ be responsible for providing a grouping menu for emulators who cannot read SD card files? If we're going to put in work, the work would be better spent on said homebrew.

As such, the only homebrew this would not affect is jEnesisDS, due to it's WEIRD codebase. Since PicoDriveTWL could still be worked on instead, it's best to lay this idea down.

Basically, the gist of this idea was to be able to pass a container (technically .img but you could think .zip) of ROMs to an emulator.
