whereas I have to boot into a crappy WinXP live CD to use the GB Transferer 2[/quote]
Hello taizou
you can use the GBT 2 software with Windows 7 by choosing the XP compatibility mode. No problem here.
I have a little question: On your hp I read you found two more Mani 4 in 1 carts. Can you do a dump of this one please?
http://hhug.me/?post=5I don't know if it can be fully dumped but if you can read the menu (32k?) it will maybe be enough to reconstruct the complete ROM image. Thanks in
advance.
btw I did redumps of Thunder Blast Man and Jurassic Boy II. I'm not sure if they are correct though. There is a strange phenomenon regarding the Sachen custom
logo which I don't understand yet. The scene dumps do not have a custom bootup logo but contain just the regular one. My dumps actually have both just like the Beast Fighter dump I did earlier. But: There are raw reads of two of the 4 in 1 games made with an EPROM programmer and they do not have the Sachen logo while a read from the pins actually does.
It is possible the custom logo is not stored in the ROM chip but somewhere else on the PCB and mapped into memory by the special mapper they use. So technically
a correct dump would just contain the regular one. I'm not sure though if this is really the case and if it applies to all their releases or maybe just the multigame-
carts.
My dumps also got bad checksums which I think is correct as I don't believe Sachen would care about correct ones. Probably the scene releases fixed these.
Ignoring the header/logo my dump of TBM matches the scene release perfectly. JB II however is different in several places. It might be a revision, an incorrect dump
or the former release was hacked.
Last but not least can you please explain what you did to "fix" some dumps to 4 MB? Did you redump them at 4 MB forced or is there some special sizing-up treatment I don't understand?
Little update: My copy/dump of Jurassic Boy II appears to be different in some way regarding tiles etc. For example the title screen shows Sachen(R) below the Jurassic Boy II title. The dump in the net does not. Can anyone check his copy of that game? I know there is a chinese label variantion of that at least. Maybe one shows the copyright, the other does not. Or possibly the one in the net is a pirate copy.
