[feature request] rom=<url> parameter in https://binbashbanana.github.io/webretro/?core=handy

[Fabrizio-Caruso]

I would like to use your JS port of the handy emulator at https://binbashbanana.github.io/webretro/?core=handy to let people try my 9 home-brew games (which I can build for a multitude of targets) as I already do for some machines through JS emulators (see my games on the browser at https://github.com/Fabrizio-Caruso/CROSS-LIB/blob/master/docs/GAMES.md#trex)

If I try to load my games with your handy core with

https://binbashbanana.github.io/webretro/?core=handy&rom=https://github.com/Fabrizio-Caruso/CROSS-LIB/releases/download/AtarLynxVersions/Xstinger_atari_lynx.lnx

I get this error about not founding the rom:

I have also tried to use http for the location of my roms.
Your emulator may have an issue with redirection.
It is a pity because GitHub repository is a nice and free place to keep binaries.

If this appears technically complex, we can look at how the other JS emulators manage to load roms from GitHub.

For example:

This is not a bug.

They appear to use a php page as a proxy, which is not possible with how this project is hosted

[Fabrizio-Caruso]

@ethanaobrien I see it is blocked. Do all other emulators rely on PHP? If you won't or can't implement this for technical or other reasons, is there a way I can use your emulators with GitHub repositories? Do I have to host them elsewhere?

[Fabrizio-Caruso]

@nippur72 how is your emulator circumventing GitHub? I don't remember you telling me you were using a php proxy. I thought it was pure Javascript. I may not remember well.
