Looks like someone else likes Bleach.
So how about some pointers on how to replace game startup animation?

I would think that when this particual flash chip was developed, the specs didn't call for numerous writes so the gates are probably not quite as resilient as the ones in general purpose flash memory found in mp3 players and digital cameras.

Flash memory has a finate number of times you can write to it untill it breaks down, so we want to avoid frequent writes as much as possible.

MomDad, it does work.
But I just found out that there is no support for anything other than english and japanese in the browser. Here I was hoping to save space on the memory card. Sigh, back to converting cyrilic text to pictures.

Possible overflow exploit found (maybe fake?).

It appears a group of people found a way to exploit memory overflow in the Thug 2 game.
Here is a link to the forum where it has been announced:

They have not released the code as it seems to make PSP "act weird."

eBooks on PSP

Hopefuly this is not going to be regarded as offtopic.

In this new version I added an option to transfer yo...

I doubt that there is a watchdog for page fault. There is probably a convention for creating PSP code that the current process must kick the dog or else it gets shut down. So you lock up the browser with this DoS attack and the counter on timer is not reset any more - your PSP shuts down.

The problem with moving to html from simple text file is that you have to parse the tags to get formatting right. Plus the pictures probably have to be resized to fit each page.

PSP doesn't care about filenames. It only cares about dates of creation. Could it be that when you copy the files you some how mess up the time of creation? For example, if inside the folder you have files organized by name rather than by date and you copy stuff over, windows will copy them in order...

You see this size because manufacturers of harddrives and flash memory decided that it's nice to say that one megabyte is 1000000 bytes, not 1024x1024 bytes. So there you have it - 512megabytes on the ad turns into 488 real megabytes.

The thing is... This screen is not generic, it is different for each program. I take it you are trying to print from a web-browser. If you open word and go the page setup, you'll see a screen that resembles the one you posted.

To get this screen, you need to go to Page Setup, not printing properties.

Here's another thing that might mess up sniffing the communication.
The goal is to read firmware as it is loaded from Flash to RAM, right?
Suppose that the chip has some logic to directly pump content of Flash to RAM. So connecting to traces would do you no good.

Is this board more than double layer? If that is the case, then attaching to the lines on the PCB might be very difficult (some traces are on inside the board).
