Thanks for the review! ;)
As for the music editor, I registered an enhancement issue so I don't forget about it:
https://github.com/haroldo-ok/vcs-game-maker/issues/46
As for the emulator problem, I would need more information to see what went wrong...
- There are already a few known bugs that happen when you edit the background or the sprites, that are marked to be fixed in the future:
- https://github.com/haroldo-ok/vcs-game-maker/issues/17
- https://github.com/haroldo-ok/vcs-game-maker/issues/19
- If those happen to be the error, until the bugs get fixed, a workaround would be to, after finishing editing the images or the sprites, choosing the "Actions" tab to make sure the ROM is updated.
- Also, there is a bug that may happen if you happen to have a small screen:
- https://github.com/haroldo-ok/vcs-game-maker/issues/14
- If that happens to be your case, until the bug is fixed, an ugly workaround would be to reduce the browser's zoom (on most browsers, <Ctrl> + <->decreases zoom and <Ctrl> + <0> resets the zoom)
- If you open the browser's debug console, does some error message appear on the "Console" tab? The browser's debug console can generally be opened by pressing "F12".
