What I can do to help:
I would love to translate this game. I've done a lot of freelance game translation and currently work as an in-house translator/editor for a game localization company full-time, but would love to work on my own projects for games I really love too (and that will never get localized). Unfortunately, I don't know a thing about programming, coding, messing with ROMs, and the like, so I really can't do a single thing unless I can find somebody with experience in the aforementioned tasks who'd want to help me on this project...
Well, well, this is some high quality request
It's usually the other way around, people who know coding for PSP but can't get actual translators and some even resort to Babelfish the whole thing
You should really open your own thread in this sub-forum and I'm very confident someone will chime in
That said, even though I can't help you much with PSP games, I really encourage you just to get familiar with the process.
Take apart any given Nintendo DS game (as a learning experience, since it has a file tree, a tool called Tinke that separates known file formats), for example Japanese versions of already localized Nintendo games.
The reason being Nintendo DS games (along with NES games) are generally (but there are nasty exceptions) the easier to modify.
Once you manage to hex-edit a text (with hex-editors), sometimes you'll even need to modify the font with a tile editor (like tile molester, and crystaltile2) and put "hello world" instead of the original dialogue, you're all set.
And hex editors can help you modify all sort of stuff, be it sound, music, lives, programming (not the ideal solution with a hex editor alone, though ), how the existing tiles are arranged to create level maps and title screens, etc.
This knowledge is then applicable to every game on every system that can be recompiled into a working build on hardware (read: every hacked system that can read modified ISOs/ROMs) - except the Atari 2600 maybe.

PSP is the same as DS editing, except:
* getting the ISO file from UMDs/PSN downloads: you can install a CFW and it will just appear on your computer, ready to be copied. Tutorials exist online.
* modifying graphics: tile molester, crystaltile2... maybe some compressed files, you can figure them out by reading the game's programming
* modifying text: hex editors (ideally with tbl support)
* rebuilding modified isos: Instead of Tinke (for DS), there's UMDGen - and alternatively UMD-Replace (check romhacking.net for these tools and more)
* text shows with wrong width/only accepts double-byte text/compressed graphics that can't be modified (and I bet this is the case with Summon Night 4)
- in short: you need to change the programming aka "assembly" (well, this stuff can only be done with emulated consoles generally): get someone experienced, or learn mips assembly - then get the debug build of the PPSSPP emulator and track down whatever changes and which you need to modify.
A programmer background (in C/C++/Python/Java/whatever) also helps, since you can code tiny tools to automate the above tasks if they are too tedious - for example, you can code a custom tool for a given game to make it spit out the text as nice clean txt files, and insert it back in the original file format (that's called coding a text dumping tool and a text insertion tool - other solutions for this task exist too )
It's not as hard as it may seem. You could even translate many games only knowing SOME of these aspects (often, the assembly won't be a requirement for simpler games, or games thought for a localization)
And i forgot something - the console-specific parts in romhacking are:
* Some tools made for widespread file formats on a given console (example: GIM/TIM for PS1/PSP, ARC for NGC, NTFR for DS,...)
* The emulators themselves
* The assembly language, which changes entirely with each console (it makes sense, after all) and needs to be learned again (mips for PSP/PS1/N64/Saturn (there are variations), ARM for GBA/DS/3DS, PowerPC for GC/Wii/WiiU, X80 for GB/GBC/VB, c6518 for NES/PCE/SNES, 68000 for Sega MD, ....)

Of course, you can even offer your translation skills without bothering with the rest if you find someone willing to do it.
GAME NAME: Starry☆Sky-in-Spring Portable
Why it has to be translated?
Well if you look at the series there are I think 8 Psp versions of this Starry sky series and It looks amazing.it isn't adult rated like a few other Visual novel psp games however it has a amazing storyline and it really would be great after it has been translated. So I ask any one who is up for taking the challenge of translating this game please please Do. Thank you.
What can I do to help?
I can't do much at all but I can possibly get help if you run into any troubles while translating this game. I am willing to proofread and help iut in anyway I can.
To Ghamni can you add it to the list know please?
Oh, that's much better looking already
Hopefully someone is interested by this - I'll add it to the list
