    Netlink ROM dumps

    Yes, recent Shiro show started another wave of "new netlink" (or should i say "Novalink"? ) talks. There are many opinions and visions, i have mine as well, but i suppose it's a bit off-topic here. In a few words, serial ports can provide speed up to 2.2 MBit/s (that's the channel speed, actual...

    Netlink ROM dumps

    I dumped my netlink ROMs, leaving them here for anyone wishing to dig deeper. First one is MX27C1000, 128Kx8 EEPROM connected to L39 MCU. Surprisinly it contains a lot of strings from different x86 motherboard BIOSes, this is either Rockwell being lazy, or chip being used elsewhere and not...

    sega saturn save converter

    Physically on a real hardware saves are stored as a small "metafiles" inside a bigger storage (either internal, cart or floppy). There are 2 kinds of emulators: first ones use entire storage image as a file, second ones store each "metafiles" as an independent file. IIRC both Yabause and...

    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.
