Is there any way to port Ikachan to PSP? It's folder structure / file system seems like it would be easier to port.

There was a time when Pixel gave out the source code for Cave Story to those who could create a working demo of their port of choice. During that time no-one ever asked for the source code for Ikachan. Now it is likely too late. If you want a PSP port (or any non-windows port) of Ikachan you will need to manually reverse engineer the Ikachan executable. Fun, no?
Although there is a commercial 3ds port if you need some Ikachan on the go.

Okay, I might actually attempt to port this (no promises, I'm not that good at this kind of stuff). And I realize there's one on the 3DS, but I just prefer the feel of the PSP.
EDIT: Getting the source was remarkably easy. Unfortunately I have no clue what to do with it XD
I'll attach a .txt with the code in it so hopefully somebody *cough*Noxid?*cough* can help with this!
EDIT2: It's in a .zip because the .txt was too large.

How? I know a very small amount of Assembler, and that looks like it to me.Dunc2403 said:

oh lol, I said I wasn't very good at this 
I'll keep trying though.
EDIT: Assembly is basically just a more complex version of C correct? So shouldn't being able to see every small step make it easier to port?

Assembly is the textual equivalent of machine code as it is executed under that platform's native instruction set. It is not by any means a portable language because for example the instruction set of the PSP is vastly different to that of a Windows PC.

Ehy, I'm only 11 years later! 
Btw, I'm currently porting the ikachan decompilation source code. Basically it almost use only windows.h as main library. The way to port this game is to do the following roadmap:
Compile the decompiled game and test it -> port it to SDL2 for video -> write some helper function to port the PiyoPiyo audio system from DirectSound to SDL2/SDL2_Mixer -> Compile it on PSP.
At the moment the game runs fine (with some minor bugs). I didn't port the PiyoPiyo audio system at the moment, so there is no audio. I don't know anything about the psp hardware (I have a better background for tile based consoles) but it is powerful enough to run it at full speed.
Probably the strangest bug is that the game crashes if the game scene is displayed behind the menu item. I don't know why it happens, the game works fine if the SDL port is compiled into a .exe or even in .wasm for the browser. It may be a bug of the SDL2 port.
