Arcade Rom Patcher (V15)

[GadgetFreak]

The JROK conversion you link was quite straight forward as CPU2 in Sky Kid Deluxe doesn't do anything really so was simple to remap. In Ishtar it does a lot more and would require a lot more remap work.
Remapping a game is usually not that difficult but it can take a considerable amount of time depending on how the game has been programmed. It is always much easier if the mapping is handled by a PAL/GAL as this can then be modified and is much simpler.

Presume you realise that Tower of Druaga is not a Namco86 board but a Mappy board. Same rules apply for remapping as above.
Remapping is generally simpler than adding Freeplay as detailed code flow does not need to be studied but it can take considerably longer as it can be a time intensive task to catch all address changes.

Since V14 I can't execute Arcade Rom Patcher ; the program starts and on the bottom of the splash window is written "!!! WARNING SLICE IS CORRUPTED !!!". When I click "OK" the software exits. Is it due to the usage of Win7 ? Thanks

I have been using my personal signing certificate since V14. This is a way for people to be sure it is my genuine software.
If you right click on the icon and select Properties then select the Digital Signatures tab you should see the certificate.
It is also a way for me to verify the software hasn't been tampered with or become virus infected when it is run as I can check the signature.
I would imagine you either have old master certificates on your windows or the Patcher program has got modified somehow.

I did a search as windows XP had this issue before. I found the following MS link for Certificate updates on old Windows:

Also try adding the exe to windows UAC , if it starts and closes its normally that. Search web on how to do it, very easy.

@ GadgetFreak and TheDaddy : Thank you for the replies, I will try.

I have an original single board Lady Bug that I want to patch but can't seem to find the right MAME romset. Arcade ROM Patcher lists version ladybug8k which I think is what I need.

Do I just have to dump the original ROMs myself and then patch them? No big deal, just wondering.

Yes mate just stick the rom in a folder , Select that folder from Patcher. Then just click patch and it will do the rest

As far as I know, mame only has the double board version with more eproms. You might have to combine 6 roms into 3, patch them and split them. I will look into it tonight if you want. Actually theDaddy just said what you have to do.

Yeah, just surprised the ROM dumps for this version don't seem to be in MAME.

Also, the dump of ROM 1 I did isn't recognised by romident or Arcade ROM Patcher, but the game works fine. 🤷‍♂️ ROMs 2 and 3 patched fine.

 

[big10p]

Looks like ROM 1 has been replaced at some point as it's different to the other 2.

The 8K version is not an official Mame set but is just a combined version of the standard one, it's what I run in my board.

Ok, but I'm not sure which files to combine or how to do it tbh. Still new to this lark. I'll see if I can work it out...

 

[big10p]

Nope. Can someone tell me which 2 files in ladybug.zip I need to combine to make the ROM 1 8k file I need, please.

See the line 718 in this mame driver https://github.com/mamedev/mame/blob/master/src/mame/universal/ladybug.cpp

You need to combine
L1 +L2 into 2A (This should be your ROM1)
L3 + L4 into 2C
L5 + L6 into 2E

Without a picture of the PCB is hard to tell where rom ROM1 is. Does the checksum match with the one in this file?

// also found on an original PCB with 3x 0x2000 program ROMs (identical code-wise)
    //ROM_LOAD( "2a", 0x0000, 0x2000, CRC(b01c773b) SHA1(4e79eba05e92a614f707488b0e4245f3f86f2531) )
    //ROM_LOAD( "2c", 0x2000, 0x2000, CRC(600b7302) SHA1(bd933d22e261f7d8e37a514725dcad204fab0c68) )
    //ROM_LOAD( "2e", 0x4000, 0x2000, CRC(9a96396a) SHA1(d355092ef1666e4fd4479160c9baf4dffcbad4c5) )

Thanks very much. Yes, it's ROM 2A I need. I guessed it was probably L1 and L2 that need combining, but when I tried it, romident didn't recognize the file. In the programmer software, I loaded L1 into the start of the 8k buffer, then loaded L2 into the buffer at 0x1000, making sure to retain existing buffer content. Maybe I did it wrong?

You can use this romwizard tool to combine or split roms. Easy to use. https://www.wolfgangrobel.de/romwizard.htm

Thank you. I'll give it a go.

It can be done but I don't have any time at the moment. Perhaps later this year.
