DoPSBox - DOSBox PS3 Emulator in Development by Robo Hobo

550°
194w ago - Today PlayStation 3 developer Robo Hobo has announced that a port of the DOSBox emulator for PS3 is currently in development.

To quote: I'm gonna go ahead and announce my intent to port this (along with SDL) to the PS3 cell SDK. There's still lots of clean up to be done, but I've got dosbox running, including games (I've only tested 'Eye of the Beholder'). The SDL port is still missing audio, mouse, and joystick support.

I'm curious if anyone has any ideas that can be used to allow this to be used to its fullest without hooking up a keyboard. Any ideas on how to mount and load the games, or handling kb input in the games would be appreciated.

Hopefully with an SDL port, other apps can be ported too (that SDL version of mame is looking pretty juicy).

I'll post again later with a link to a code repo. For the curious, here are the code repos for SDL and dosbox. It still needs quite a bit of work, so I wouldn't go too far out of my way to build them yet.

For those who are interested to build them, this guide below which has been taken from the source code page wiki might help you.

How to build:

•First install sdcell (http://code.google.com/p/sdcell).
 

GT5: Grind A-Spec PS3 Project for Teensy Development Boards

550°
200w ago - This PS3 project might help someone out there to use their Teensy development boards for at least something, I call it my GT5: Grind A-Spec babysitter.

I got the idea from a mate of mine who used a keypad with paper wedged in to keep the enter key depressed and a controller with rubber bands and presstic. I don't own a usb keuboard or keypad, so I asked some questions and did some reading and this is the result.

Keep in mind I know nothing about programming and I can not help with other development boards.. although the code is very simple, I had to ask for advice.

Thanks to Paul at PJRC for doing the code for me.

1. Download and install Arudino Software
2. Download and install Teensy Loader
3. Download and install Teensyduino installer
4. Run the Teensyduino installer (You must select the location where you extracted the Arduino Software)
5. Run the Arudino software and the Teensy loader
6. Plug in the Teensy development board into a USB slot
7. Copy the following code into the Arduino software

PS3MrEnigma on PS3 LV2 Kernel Reversal and Memory Hooks

500°
217w ago - Spanish PlayStation 3 developer PS3MrEnigma has recently started a blog (linked above) sharing his experiences with PS3 LV2 kernel reversal and memory hooks.

Below are the details thus far, roughly translated:

In this post we will see how to make hooks (hooks) in the LV-2 SYSCALL. The possibilities are endless da hook, only to be limited to our imagination and what we want to achieve with the hook.

For this section we should bear in mind that we need to meet the following requirements:

•Having a dump of the entire LV-2, possibly without being modified in any way by a payload.
•Knowledge of assembler to understand the original SYSCALL to create our hooks.
•Understand how the / s SYSCALL we will modify.

For this post'll take the example of a LV-2 3.41 Debug (for it is that I work mostly), but can be applied just as in a LV-2 Retail.

The first thing you need to know is the beginning of the SYSCALL_TABLE, and the number of SYSCALL we want to put a hook.

For example put a hook to the SYSCALL 0 – 363 (867) to alter the machine model that we will return.

The SYSCALL_TABLE is at position 0 – 303130 (at any position in the LV-2 assume that they add the base address 0 – 8000 ...), knowing the number of the...
