    Jo Engine: JO_480p Makefile Option

    Oh, i forgot about this test, sorry. The cable arrived, i tried outputting hires with my own code, and 480i worked with 448 lines but failed with 480 and 512 lines (there was some image, but completely out-of-sync). Haven't tried 480p yet, will try today.

    Simplest Way to Add Files to Saturn ISO?

    Keep in mind that dd does not support multiple input files, so to insert IP.bin back, you'll need 2 steps, something like this: cp IP.bin complete_image.iso dd if=changed_image.iso skip=1 bs=size_of_IP_bin >> complete_image.iso where you replace size_of_IP_bin with a real value.

    Simplest Way to Add Files to Saturn ISO?

    You can extract IP.bin with dd, then add the file with mkisofs, then insert the IP.bin back. Or, if you have the IP.bin already precompiled/available, you can skip the first step.

    Jo Engine: JO_480p Makefile Option

    I have a TV with a built-in SCART. Digital one though, it does some kind of an auto-sync magic when i connect an old i8275-based PC, so the test might be not very authentic. Don't have any Saturn-to-scart cables, but i can probably solder one, or maybe order somewhere. I will check if any of my...

    [Sega Saturn] Power flashing

    There are hundreds of possible reasons actually. Without proper equipment it's really hard to tell what's going on. Did you replaced PSU with a compatible one, or just a random 5V&3.3V source? Some saturns have two different 5V power rails, one for system, and another for CD. Have you measured...

    Anyone have those old planetweb gamexch Saturn saves?

    Thanks, that's a big bunch of saves. I improved bootable carts support a little, parser now loads more images from Pseudo Saturn Kai iso, but not everything yet.

    Anyone have those old planetweb gamexch Saturn saves?

    Thank you for your dedication as well. By the way, the archive with saves mentioned in this topic is missing. Can you please re-post it? I was thinking about adding a planetweb mode to parser. And about a web save archive, did someone took the initiative to make one? How is the progress?

    Anyone have those old planetweb gamexch Saturn saves?

    Ooopsie. The header is corrupted a bit, but nonetheless, there is no (known) save media with a cluster size smaller than 64 bytes. Fixed that one. Anyway, you can always override the autodetected settings with a correct ones (provided you know them).

    Saturn Case mod

    I believe they're 5V. At least I've added 5V access led to my US unit, and it works fine. If you want to add access led to your system, check this link (it's japanese, but pictures are self-explanatory): http://www.geocities.co.jp/SiliconValley-S...8/ss_acsled.htm You will need to add a...

    Power Memory questions

    Judjing from the official RAM backup PCB, it contains only one constant value, 0x01. It can be set to the I/O bus if corresponding values at cart address inputs are set (i'm not sure if it's 0x24FFFFFF, but it seems to be larger than 0x7FFFF). And one more thing, it is set with customizable...

    How to MAKE a modboard ?

    Hmm... why dumping the IC program is the first thing to go? What about writing microcode it by yourself? Or even connecting your PC as a gigantic modboard... Basically, recording signal from CD-board to motherboard while inserting backup and original is a simple way to get difference between'em...

    Saturn Backup RAM

    Well.... looks like nobody's using this stuff... but anyway. Just released v0.3. There are still some known bugs (incorrect SAT calculation in saves more than 400+ blocks, and missing country/time support in raw mode), and a lot of unknown. I'm waiting for bugreports. And finally I'm going to...

    How to MAKE a modboard ?

    Well, it is possible if you've got digital oscilloscope (one of those analog-to-digital PC cards), Saturn schematic circuit, and helluva much time.

    Saturn Backup RAM

    At last, just finished v0.2. Now it supports all I need (if you need something else, mail me), but probably with some bugs. Save insertion is debugged only in no-AR no-header mode (IMHO it's the most difficult), and I'm not sure if it will work correctly in other modes. Another problem is a...

    Saturn Backup RAM

    Oops! I just found a serious bug, it caused failing extracting save. If someone ever downloaded this program, please do it again.
