Memories Off 2nd, Never7, Remember11, Ever17 and I think more of such stuff from Cyberfront use similar format (but not same! Container is same, but script format inside is different, means text opcodes).
I am actually do not port anything right now, as I told this would take enormous time for me alone to do all that. Need at least a person who could copy-paste strings in Notepad from one window to another, removing unneeded characters and checking in Google if it is correct string

Without such person max I would do is hacking the format (if I really would be able to do that) and stop. Or if I really do not loose my spirit (that's unlikely) I could indeed copypaste whole script from PC to PSP, but, well, in this case this would be in 2020
Another thing is to find IOS version for Ever17 and others, as they were removed from stores and not possible to buy them anymore. If anyone still have that, please send me a PM, as I think they have exact same format as PSP version and the data could be also transferred to them too... Think this would extend the audience, who want to see that.
And if aim for VN, which were only released for PSP - there is a problem, where get translator for them?
