![]() V0.155 V5 CHT2 bad \crashes instantly (shortly before CreateEventW) Then on the other hand, I am not really familar with c languages either.įor the CHCD stuff, the rust metadata.rs file assingns "CdRomOld = make_tag(b"CHCD")" but I can't see any code that is handling that CdRomOld type (maybe it's unsupported?) but I haven't found any code that handles the newer CDT2 stuff with things like PREGAP either (and I guess it must support that somewhere?). The comments are neat, and the source looks more compact, I haven't looked too close at the actual code and don't know yet if I can understand the rust language. And create some MODE1/MODE2 toc/bin images with different sector sizes for examining the old CHCD metadata. I'll have to learn about LZMA and FLAC decompression next. ![]() It doesn't waste too much memory, but the sectors could have been a few bytes smaller with better filtering. but most sectors do contain the original unfiltered sync-marks (looks like a bug in the compressor), the sector header with MM:SS:FF:Mode bytes isn't filtered at all. It does have ECC bytes filtered out (which is good), and some sectors do also have the 12-byte sync mark filtered out. I've got the "cdzl" compressed file working, too. Having v0.218 would be neat, too, I guess it won't help for anything, but it would be nice to see if it's giving the same error message as v0.246. Or something between v0.159 and v0.174 (you could narrow those down with a hex editor and searching for the first/last version with/without string "AddVectoredExceptionHandler"). I am afraid that V5 is seamlessly switching from one problem to another.īut maybe something between v0.150 and v0.159 could work. V0.246 V5 CHT2 bad -64bit? -requires "newer version of windows" V0.174 V5 CHT2 bad \missing KERNE元2.DLL:AddVectoredExceptionHandler I will not write some "how-to" in my guide -)Ġ registered and 15 anonymous users are browsing this forum.Code: Select all v0.146 V5 CHT2 bad \says output file already exists (crashes on -f force) I will write in my guide going back to an older version is only recommend if you need that for a special reason (old device,portable). And actually distributing v4 CHDs is one sure way to draw the everlasting ire of MAMEdev. Is there some reason you're doing this? I have to strongly caution against putting anything back into v4, as it omits data that is important for correct emulation and "misplaces" some other data (it also gets much worse compression ratios on some games, but that's not as big of a deal). Verify and info has passed but I'm not 100% sure if this I have tried to extract it to a raw-file with v5 and compress it Verify and info has passed but I'm not 100% sure if this works really. I have tried to extract it to a raw-file with v5 and compress it again to a chd with v4. You would have to write the image to the device (HDD, for example), then capture a new image with an older CHDMAN. I don't believe it can be converted back. Re: converting chd files to an older version Maybe someone can lead me into the right direction -) ![]() Or must I convert it for example with two steps ? Like extracting it with chmdan V5 and creating a new chd file with chman.exe V4 again. When I have converted my chd-file to V5 -> is there a way to convert it back to V4? I'm trying to write a MAME guide and one of the topic is "rebuilding for an older set".
