What’s new: 

– Program optimization. The game should have much less slowdowns now (ie it should slow down only where the original Bubble Bobble slows down!)

– Bootleg support. The game can now run also on most bootleg “Bobble Bobble” PCBs (or on emulated bootleg clones, should you want to do it). Forget the crappy bootleg behavior: Lost Cave works on bootleg boards just like on the originals.

– Difficulty rebalancing. The game has been carefully rebalanced, based on one year of user feedback. It *should* now be possible to complete it with one credit. Greater contributors are even acknowledged in the end credits of the “Super” Mode!

: if you want to play the game with an emulator, all you really need is the file. The additional bootleg files are necessary only if you want to convert a real Bobble Bobble / Super Bobble Bobble bootleg board into a Bubble Bobble Lost Cave one. Please read the readme.txt file for full info, or email us.


OLD VERSION (patch only)


This is the patchfile for the 1.1 version of Bubble Bobble Lost Cave.

From readme.txt:

Usage of the Patchfile (under Windows)

1- Look for the file in the ROMs subfolder of your arcade emulator.

2- Don’t unzip it. Just copy it, as it is, in a folder of your choice.

3- In the same folder of your choice, put the ApplyPatch.exe AND the here enclosed Don’t unzip it

4- In thie folder you should now have these three files:

5- Double click on ApplyPatch.exe.

6- DONE! Or at least, it should. Please check the ApplyPatch.log textfile.

7- a has appeared in the folder. It’s the newly created Bubble
Bobble Lost Cave Romset!

8- Put it in your ROM Folder and play it with your favourite MAME Build, but…
Which Emulator should you use?

Our recommended first choice is MAMEUIFX because it supports Bubble Bobble Lost Cave natively. You’ll see the voice “Bubble Bobble Lost Cave” in the UI menu!

Thanks to Mamesick, from MAMEUIFX version 148, Lost Cave v1.1 is supported:


If you want you can use this lovely 1-game-MAME which runs only Lost Cave, thanks to Lost Cave kind friend Tormod. Check it here:

If you wish to use the latest OFFICIAL MAME build which you can download here

please remember that you have to rename from to and
make MAME start from commandline with

mame.exe bublbobl

Basically you need to temporarily SWAP your original bublbobl romset with the
Lost Cave one.


Another great, fast emulator supporting natively the game is FB ALPHA:

ONLY for this emulator, you’ll need to manually rename the roms of the just created Unzip it, rename, re-zip. You may make a batch file out of the following guidelines:

rename a78-05-1.52 lcave05
rename a78-06-1.51 lcave06
rename a78-08.37 lcave08
rename a78-09.12 lcave09
rename a78-10.13 lcave10
rename a78-12.15 lcave12
rename a78-13.16 lcave13
rename a78-14.17 lcave14
rename a78-15.30 lcave15
rename a78-16.31 lcave16
rename a78-18.33 lcave18
rename a78-19.34 lcave19
rename a78-20.35 lcave20

Remember: this manual process is needed ONLY for FB Alpha.

No ROMs included here! And don’t ask for them.

    • Would you mind sharing your setup? I cannot get it to load with any of the retroarch cores nor filename schemes.

      • Hello, I’ll try and update it all in early 2018. Please note that the game is so far supported by the official MAME release (since a couple of years). This should make it even easier I guess. Thanks!

  1. I’m unable to get the bootleg code to work. I’m running it in MAME before I put it on my board. I get the startup sound and the scores flash for a second but then all I get is an unresponsive black screen.

    • Hi! Sorry for the late response – hope you did not quit trying:) If you still need help please let us know. The game works flawlessly on our two bootleg boards, so…

      • I think I figured it out. With attract sounds enabled, the game doesn’t boot (same with my board). MAME has attract sounds on by default.

    • Wow, saw this one just now (9 months late!) sorry! As far as I know the game cannot run on mame4all, unless someone builds a custom build for it made especially for Lost Cave!
