    Action Replay Save Format?

    I can't remember the exact cases of SAT being non-contiguous, but i remember fragmented saves with the second cluster being away from the first one. They were relatively small, so SAT was probably completely in first cluster, but i think nothing prevents SAT from being fragmented. And even if...

    Action Replay Save Format?

    "BackupRam Format" is a signature sequence that allows BIOS to detect if the media is formatted or not. If there are at least 4 copies of this sequence at the start, the media is considered as formatted. The number of these sequences determines the cluste size (4 = 64 bytes, 16=256 bytes, etc)...

    Action Replay Save Format?

    @slinga , the code you mentioned simply adds 4 "BackUpRam Format" lines to the beggining of the image. The replace() function is a member of QByteArray class, it replaces a part of array with something else without changing the array size. Extra 0x00s should not be there after RLE...

    How do games address save files when loading a game save?

    Cartridge is on A-Bus interface, while backup is on C-Bus (or CPU-Bus as the block diagram implies). The A-bus is accesed thru SCU and C-bus, but the C-bus is accesed directly, without any SCU usage. So the SCU is probably not the culprit. One probability of what happens is that someone on...

    saturn save converter

    Quick answer : No. It could be possible if you a) verify that ASIC in X-band maps the flash into the start of A-bus CS-1 and manually re-map it with some glue logic if not b) hack the ID code at the end of A-bus CS0 to be backup RAM, not netlink (hardware way, and you will probably completely...

    saturn save converter

    Export degradation in ss-save-parser is fixed, i released v. 0.9.8. BUP support is working, but was tested lightly, so use with caution. To export file in BUP format, choose the .BUP (case-insensitive) extesion while extracting. Latest release

    saturn save converter

    @dibz, it's probably funny date/times and broken allocation tables why yabause skips them. I tried to extract them for further inserting into a clean image, but suddently found that parser 0.9.7 is broken and cannot extract at all. I will fix that degradation asap and will retry a bit later.

    Game Saves collect project

    Parser does not work with the save content, it only copies the them from/to image file. And i'm afraid your question is very game-specific, and there is no tool to do this. But you can probably do it yourself with a bit (or a lot) of hacking and comparing saves from a different versions. How do...

    HELPP!! Glitchy Grapichs on VA07 Saturn

    First things first, is the power correct and stable? Have you checked/replaced the capacitors? If not, check it first. From the look of your glitches, i'd say it's either VDP2 or VDP2 VRAM. Cold solder is probably not the case, because the soldering was done with a wave. More probable scenarios...

    saturn save converter

    I was talking about SSF support in my parser, not the SSF itself :) Sorry for confusion. Regarding the export, try simply adding ".bin" to the file names when extracting them. There should be a question about overwriting existing files, if it appears. then you're probably doing it right. And...

    saturn save converter

    It's there in the resources, but maybe not the latest release. You can get a fresh one from github: Release 0.9.6-windows · hitomi2500/ss-save-parser Unfortunately my SSF experience is very limited, so i'm not sure if it needs additional magic, but from the looks of it, you should open...

    saturn save converter

    What converter are you talking about? Is this the one? (your version might be without fancy button pictures). This one is mine, and i can help you with it. If it's something else, please post the screenshot. Regarding formats. iirc yabause uses a single image for all saves. The exact image...

    Action Replay Save Format?

    Oh, did you mean getting saves off the raw cartridge image? I thought it was about AR export tool for PC via DB25 connector (i had one AR like this, but it was lost sadly). I don't know if the tool like this ever existed, but how did i got this file anyway? For raw cartridge, ss-save-parser can...

    Action Replay Save Format?

    You can detect AR by the bootcode header located at the start of CS0, i.e. 0x22000000. It is almost equivalent to IP.BIN on CD, and should include "ACTION REPLAY" and "DATEL ELECTRONICS" lines within first 256 bytes. Might differ for a new chinese ones. As for export format, i have an "AR-like"...

    Saturn 2 Poll

    While i totally like the idea of recreating the Saturn on a novel hardware, changing the core system (to make it "2") i can live without because of obvious reasons. At the first stage one can remove the obsolete non-proprietary infrastructure like memories and build a glue fpga-based structure...
