Kene Touhou Mohofu - lela.null - 09-22-2013 04:24 PM

This is the second game I have tried playing on ppsspp gold for Android. It is a homebrew of Touhou. The game icon shows up saying I installed it correctly. But when I try to play the game it says "missing key". What does that mean and how do I fix it?

Homebrew of Touhou?Do you mean DLC?Or is it a demo?

Many demos needs a key that ppsspp don't have.

this is where I downloaded the game.

Edit by vnctdj : Even if downloading homebrews is not forbidden, the site you mentioned contains commercial games' .iso files, so this link is not allowed.
If you want to share this homebrew here on the forum, you have to find another download link which is "clean" or upload the homebrew yourself Smile

To play you need to convert " EBOOT.PBP " to " ISO " .
that will fix this bug !

Get it from the official site:

http://code.google.com/p/kene-touhou-mohofu/downloads/detail?name=231_kene_r39.zip&can=2&q=

It also has an update:

http://code.google.com/p/kene-touhou-mohofu/downloads/detail?name=231_kene_r39_to_r40_update%E5%B7%AE%E5%88%86.zip&can=2&q=

Note: I've not tested its compatibility.

Edit: Looks like it's encrypted with key 0x60, which a lot of demos and some homebrews are using. I suppose one could compile it and then use an unsigned binary to get around it..

How hard would it be for ppsspp devs to acquire the necessary keys for demos/homebrews,daxtsu?

Original download has broken filenames breaking "story" option and comes with signed eboot which as discussed above can't be decrypted without real PSP, so here's a fixed one with correct filenames and unsigned eboot:
- 231_kene_r40 Touhou(includes source code and a folder it creates on psp ~ see below).
That's latest version of the game and as can be seen works on PSP:
[attachment=16038]

Unfortunately on PPSSPP it bugs out very early before even showing anything, very little happens before it starts going crazy so if anyone wants to check this ~ disable "fast memory", "ignore illegal reads/writes" and have fun trying to figure it out.

I didn't had much will to investigate it(I ran the game on highest difficulty level, made a faint smile and exited shortly after, not my kind of fun;p), but suspect one of the three things:
- a timing issue(always good thing to blame in japanese software;c),
- memory allocation(same;c),
- "something weird" with encoding(?) - one of the few things game tries to do before bugging out is create it's own folder on memstick under pictures and fails doing it, on PSP it ends up as "東方模倣風"(game title) on PPSSPP it ends up as "�����͕핗", through that could just be caused by one of the above.

Edit: Built the game with DEBUG_MAP(download) and lol all problematic functions seems to be related to kanji:].
