Re: leonardoliveira & Idc's clean decrypted roms

probably this is not the initial EPROMs as the label seem to have been removed once (what is your opinion ?)
If the eproms are the same or not as the original ones, is not easy to tell. Because the labels had to be removed to erase and reprogram the roms with the decrypted code.

Re: leonardoliveira & Idc's clean decrypted roms

1. It's imposible to aswer that question without having your roms to analyze. It could be either "Avalaunch" or hacked "Phoenix Edition" roms. 2. Your rom labels indicate that the revision initially was "961004 Japan" (xvsj 03 I / xvsj 04 I) 3. Yes, roms 3 and 4 are the...

Re: Raiden Fighters JET Checksum Error 9921

I'm curious, too. It seems that the hexadecimal change is about skiping the checksum test, instead of "03" as an "universal region code". Could you provide more info about this? and what is the correct address to make that change for other games ;) Sorry for the delay. I have be...

Re: Raiden Fighters JET Checksum Error 9921

BTW: I'm little bit curious about the region of your cart, since it uses the "prg2.u0221". Was it a Japanese one? The previously known Raiden Fighthers in Mame that uses that rom are U.S, Germany and Taiwan...

Re: Raiden Fighters JET Checksum Error 9921

So I have an update. A friend of mine, who wants to burn the Eproms for me told me the following: As it seems in the Mame resources my board uses the prg2.u0221 ROM and not the prg2.bin ROM. The prg2.u0221 ROM does not have the patch on the address. Ideas anybody? Thanks! Have been away during Chri...

Great, I don´t have a burner, but could ask a friend. Would you please tell me how to proceed? For the Japanese revision of Raiden Fighters Jet: Fist dump the eprom labled "PRG 2", then load the file into a a hex editor and change the byte at offset $313A2. From "01" to "03...

Would it be to much to ask for the files of the USA version with the battery still in? No one else will help. No problem, I can make a patch for the US version too. When I make the US patch I can include JED's improved "random stages" routine. Unlike the previous version that uses the cha...

Well... It's possible to use roms from any region on any board but in that case the roms need to be re-encrypted for that specific region. Because every region got it's own dedicated encryption key.

Yes that is exactly what I need. I'd be very greatfull. OK. I think the patch is ready. I have tested it briefly in Mame and it looks to me like it works as expected. But you should test it too because I'm not a great SF2 player. :D There will be 2 roms to replace on your game." sfxa.03c"...
