Re: Bubble Bobble Bootleg info

Too many hours for sure, but I really enjoyed doing it and I'm glad others can benefit of that! :-)

Now I need to find some time to put my Defender board together...

Re: Bubble Bobble Bootleg info

Regarding Bisboch / Aladar not running on MAME, that is caused by the monster speed DIP switch configuration, as someone mentioned before... it needs to be set to "Very High" (apparently the monster speed is not affected by that, it is always the same as in the "Normal" setting). I compared their ve...

Re: Bubble Bobble Bootleg info

Asure has provided some instructions on August 11th, 2013. Basically: - Re-route 74LS138 pin 1 to VCC (only). This should cause ROMs 6 and 7 to get selected for a 64K address range instead of the current 32K, allowing you to use 27C512 instead of 27C256. - Re-route pin 1 of both ROMs 6 and 7 to addr...

Re: Bubble Bobble Bootleg info

@silverfox0786

I think you just need to replace ROMs 6 and 7 by two 27C512, since this is were the treasure room bitmaps are stored. You need to check where each pin 20 goes and maybe fix the LS138 logic. Please provide more details about the connections.

Re: Bubble Bobble Bootleg info

@silverfox0786 Your board seems to be similar to Asure's one, i.e., it uses two 8700 (128K bytes) and two 27C256 (32K bytes) for the video ROMs. If that is really the case (need better pictures to confirm, including from the bottom side), you will need to replace the later chips by two 27C512 (64K b...

Re: Bubble Bobble Bootleg info

I played a bit on MAME this morning with the latest REDUX version and indeed it caused a reset on level 18 or so. I tried the version from 2013-02-07 and it worked just fine. So I guess this confirms that the latest images are not good. I also tried BB Aladar bootleg version on MAME (download link f...

Re: Bubble Bobble Bootleg info

I had subscribed to this thread to alert me on my email of any new posts, but it seems like it stopped working (I checked that nothing was flaged as spam), so I never came back here until now! Great to know that LC guys Bisboch and Aladar picked up on my idea / work and released a new pach created f...

Re: Bubble Bobble Bootleg info

I've recently stocked up on IC's to shotgun/repair games with, but my lack of too much technical knowledge stops me from doing anything further with this Bubble Bobble. I've thought up something, can we not run a LS138 (and maybe some other logic?) in parallel, and have that work when the game shou...

Re: Bubble Bobble Bootleg info

rom what I read here its some slowdown left that ain't in the original? Hi, that is correct. The only difference seems to be a somehow greater slowdown at certain levels (even the original slows down a bit there). Unfortunately I can't improve things further, since the bootlegs need to use the main...

Re: Bubble Bobble Bootleg info

Comparing to what Simon's board had, my lucky guess would be that my board maybe needs only some cuts, instead of rewiring? I think you will need to do some re-wring... First of all, it seems the mysterious 8700 is a 128Kx8 mask ROM. I could not find a datasheet for it, but the pinout seems to be c...

Re: Bubble Bobble Bootleg info

Check whether pin 1 on each of the two sockets is connected to VCC or some other IC. Those are the key points.

You may need a multimeter to confirm it if any top side traces are connected to them, since the corresponding pads are clearly unconnected.

Also check pins 20 and 22.

Sorry, you mean the treasure room still looks the same as in the picture you posted before, i.e., "empty"?

Re: Bubble Bobble Bootleg info

Hi, the crash I had before was at level 15. Does the issue happen at that level as well, when the big sprites are at 50%? Could you add a video? It may give me some clues... As far as I know, the RAM is only verified during the boot, but I may be wrong here. It could be some bad ROM data causing the...

Re: Bubble Bobble Bootleg info

Uh oh. It resets constantly. Sometimes after a few seconds on the title screen, and sometimes after it shows the basic rules. I checked the z80's they seem fine. (although they are being reset for some reason, i can see the reset line going low/high when it happens.) Inputs are broken, the board fl...

Re: Bubble Bobble Bootleg info

We used these DOS commands to create the proper images:

copy /b a78-13.16 + a78-14.17 r6
copy /b a78-19.34 + a78-20.35 r7

As I said, once you get the REDUX mod with level skip in place, it will be easy to check the treasure room and final boss.
