From what I've seen there are three ways to get a PS1 game on the Vita (and play on Adrenaline):
1: Download with that one "shop" app, but there aren't many PS1 games there because the release list was scant
2. Use PSXPackager, which is supposed to convert PS1 to eboot.pbp without compressing the audio files, but I tried this, put the folders that are named with the gameid in the pspemu/Game folder as I've seen instructed, and the Vita didn't even recognize them being there. Maybe this is the choice app, but it's a fail for me so far.
3. Use PSX2PSP, which did work for me. And it's nice that it allows for selecting an icon image, a background image, even audio. But since this converts a PS1 game into a PSP container, audio is compressed and video resolution is certainly reduced to match PSP spec. (480x272) Maybe since the games are being played on a PSP emulator, that's the best resolution possible anyway, I don't know.
