    GP32 How to optimize an emulator ?

    Hi ! I am trying to get the Atari Lynx emulator faster rewriting important parts in assembly. (The routine that displays the video data works already). Which parts of an emulator need the most cpu-power ? Rewriting which part could cause a speed up ? Either i manage to make the emu faster or...

    GP32 Assembly: What can i MOV ?

    Hi ! I am a beginner in assembly-programming but i managed to write some little routines. And what i don't understand is, which values are allowed to write to a register ? For example: MOV r0,#76800 this one works MOV r0,#76799 this one not - the compiler quits with an error message...

    GP32 GP32 + Cigeratte Lighter

    Hi ! There are some kind of PSUs for the cigarette lighter that have adjustable voltage that begin with 3V. Is it a solution ? I think it's better to use rechargable batteries. They have such a big capacity that you can play for many hours. Greetings Tobias

    FRODO Screencapture

    Hi ! I already thought of trying around with Frodo. Since i don't have many experiences in GP32 programming it will be a bit difficult - but challenging. Before i can do anything i have to know how can i compile frodo ? Is it possible with GCC ? If yes, how ? I tried to compile but it didn't...

    GP32 Assembler under GCC

    Hi ! What is the difference between ARM-Assembler and Thumb ? (As i know, Thumb is 16Bit and ARM is 32Bit - are there other differences ? When is the one or other used ?) My tries were done in 32Bit. Other question: How do i divide a value in Assembler ? (In the docs from ARM.com i could't...

    GP32 Retro GUIs for GP32

    Hi ! Really cool idea. I'd love to have a GUI that looks like Amiga Workbench 1.3. Really nostalgic. And how about an integrated Amiga Emu ? :D How about sending the GUI-idea to the author of windups ? I think it shouldn't be a big problem to change the look. Greetings Tobias
