    • Cannon Dancer/Osman Conversion -> The FREE Edition once and for all (JoeMac/Magical Drop pcb)

      So there you go, here's the free version for all of the people who'd like to have one of these.Conversion is for the JoeMac Returns/Magical Drop, not From Gonta or Charlie Ninja.



      I still need to figure out just tiny bits of this stuff, cause i'm having a little bit of gliching here and there.


      Basically, what you need to do is:

      Change 5c GAL with Osman (leave the others, mine were Charlie Ninja, previously converted from Magical Drop)

      Byteswap the AKM93C45/C46 (hold test on boot to refresh NVRAM)

      Merge 2x2 Rom files (and this is probably were i still need to figure out the order) to obtain 2x 27c322 4MB roms on location 13A and 14A (my order is probably wrong by now, or maybe just shitty chinese eeproms, still need to figure it out)

      "Adding this from Twistedsymphony post:
      13A and 14A GFX2 ROM sockets are only designed for 16M EPROMs and you
      need to install 32M EPROMs there so you need to add the A20 address
      line.
      To do that you need to cut the trace to pin 32 of the the 13A and 14A
      EPROM sockets, wire these together then wire them to pin 9 of the A11
      logic IC, then you need to run a wire from pin 8 of the A11 logic IC to
      pin 30 of the A13 EPROM socket. once you've done that you can
      concatenate 14H+14D to make the new 14A and 14A+13A to make the new 13A

      Program the rest as expected (1E, 9A, ecc ecc)"


      I'll update once i will figure out the whole thing (by few days, probably someone else has already doing it here)

      I want to say thanks to this great forum that helped me alot by figuring out stuff.

    • Thank you for sharing @TheDeath, I thought this information was already available here though? I remember a thread here about his, with all the information posted? Let me look...

      GFX Noise on an Osman [fixed]

      Look at post #28

      But regardless, thank you for posting here! It is very appreciated.

      I bought my conversion, from I think @Hammy (maybe, can't remember) and it seems to work fine. I don't think he was keeping any information to himself either, another great contributor here. (also I think I paid maybe $200?)

      If you need help to fix your glitches, let me know if my board can help, if so, I will do anything I can to help get the information out there!

      Thanks xtra, but it's not. This is the conversion from JoeMac Returns/Magical Drop. Your was from the Mitchell version wich is different, this is the data east version of the board.

      Oh yes, I see! OK, but Joe Mac Returns is a great game, I hope those are not converted! MD is.. OK, but can be found elsewhere! Thanks for posting this info! I actually think I have MD and MD+. Maybe one day I'll have all of these variants!

      Thank you for posting, please keep it up!

      Thumb up , Mo :thumbup: ... by the way , its much nicer the caveman ninja , i dont like edward randy’s slowdowns ^^ If i will find a caveman ninja board i will not proceed .im on the same boat with your thought about that
      LOL, I think ER is a very fun game, good to look at and play a few times. I would like one actually! But CN is a much better game! I will look for you if I find it I'll let you know! By the way J&M on SNES and Mega Drive is also good, and different!

      Yeah it would of been around £150. That one was lady killers or something not the magical drop people keep PM'ing me about.

      As far as i know it's a romswap + reprogram the 8 pin chip.

      I have a caveman ninja 2 prototype in for repair at the moment if anyone has a spare '233' data east (i/o) custom from this hardware.
      It IS socket all around so i can perform tests / work this out quickly but need the chip to proceed.
    • someone asked me about this the other day so I looked into it. it's not just a simple ROM swap... but it's not that difficult either.

      As you said you need to reprogram the EEPROM and the 5C PAL. but the 13A and 14A GFX2 ROM sockets are only designed for 16M EPROMs and you need to install 32M EPROMs there so you need to add the A20 address line.

      To do that you need to cut the trace to pin 32 of the the 13A and 14A EPROM sockets, wire these together then wire them to pin 9 of the A11 logic IC, then you need to run a wire from pin 8 of the A11 logic IC to pin 30 of the A13 EPROM socket. once you've done that you can concatenate 14H+14D to make the new 14A and 14A+13A to make the new 13A

      that's not all though you also need to fix the music as it will play at 2x speed since the Data East PCB run at full clock speed and the Mitchel PCBs run at half clock speed so you need to rewire the clock pin on the J13 OKI. but I'm sure @TheDeath knows that already from his Charlie Ninja conversion.

      there you go, enjoy your Magical Drop to Osman conversions :)

    • I had a spare Magical Drop so I threw one together:

      If you want to say thank you help @Hammy source a Data East 233 Custom.

      --------------
      EDIT: I keep getting PMs about this so here is a more noob friendly guide:

      This works with any of the "Data East" games on this hardware:
      Magical Drop
      Magical Drop Plus 1
      Chain Reaction
      Joe & Mac Returns

      Fix Address Map:
      Swap the PLD at 5C with the Osman or Cannon Dancer PLD for this location

      Fix Security:
      re-write the Serial EEPROM at 3H with data from MAME (this controls whether you get Osman or Cannon Dancer, all other data is the same).
      It depends on your setup but you will likely have to byte swap this data when writing.

      Wire mod to expand GFX2 ROM space:
      Cut the traces to Pin 32 on the EEPROM sockets at 13A and 14A, wire these together then Wire them to Pin 9 of the 74LS373 at 11A
      Run another wire from Pin 8 of the 72LS373 at 11A to Pin 30 of the EEPROM at 13A
      new GFX2 ROMs can be burned to 27c322s like this:
      mcf-04.14h + mcf-03.14d = 14A
      mcf-02.14a + mcf-01.13a = 13A

      Wire mod to fix Music speed:
      Cut the trace going to pin 5 of OKI audio chip at J13 (the one closer to the center of the PCB), this needs to be cut between the pin and the first via. Run a wire from this pin to Pin 5 of the other OKI chip at J14, alternatively you can also run this wire to Pin 9 of the 74LS74 at H10 as this also runs to Pin 5 of the J14 OKI.


      Burn the rest of the ROMs as normal:
      Program ROM -> 27c4096/27c4002
      GFX1 ROM -> 27c160
      OKI Music ROM -> 27c160
      OKI FX ROM -> 27c020

      Technically this guide should also work if you wanted to convert One of the Data East Games to Gonta 2
      If you wanted to convert One of the Data East Games to Charlie Ninja you can skip the GFX2 Wire mod step
      If you wanted to convert any of the Data East Games to any other Data East game you ignore both the GFX2 Wire mod Step and the Music Wire mod step (but you'll still need to do the 5C PAL and Serial EEPROM)

      Is there any difference between a Magical Drop PCB and a Magical Drop Plus 1/Chain Reaction PCB? Will this conversion work on a Plus 1 PCB?
      The PCBs are identical and the conversion process is the same

    • Guys , please , can you teach me what bytes to swap here ? Ive made the byteswap on rolling thunder 2 conversion ... there i figure it out what must to change,but here ,even is not too much on this bin, i dont know where to move ?( Thank you in advance for lesson :saint:

      ps : i hope don't mistake guys , but here is a good candidate too (you have possibility to do a offer for this) for this journey . the prices for Magical Drop seems to go higher and i write this because i paid in Japan for a board 70 Euro without shipping and now i've seen on ebay prices who exceed amounts like 250-260 usd .

      I had these in my watchlist too :

      Magical Drop

      Magical Drop

      And *this is what i've found this morning

    • Thanks @twistedsymphony, i was kind hit and miss with that. I'm not an expert at all, but i'm happy that this went throught in the end.
      I have spent a shit load of time with Strider on my MD when i was a kid (was barely touching my play time with the beast "Streets Of Rage" tho), and i always wanted to have a physical version of this game but the price it took went far away from my daily pocket.

      @AlxUnderBase MD board skyrocketed even way before this, i payed mine like 30 euros 2 yrs ago. I'm a collector since 2003 and i can probably list dozens ended up like this.
      Swapbyte should be automatic by the programmer, don't you have that option in yours? I have two shitty chinese programmers (top3000 and tl866a) and both of them did not have that option, so what i usually do is load the file in my old willem sivava programmer PCB50 (here) and use his program to do the job (vers 0.97j)
