The SRAM VCC is not connected to the same traces as the other chips' VCC. There are a couple of sot-23 transistors involved, and I had some problems following everything with an ohmmeter. I connected power, but didn't measure any at the SRAM or any other chip. Of course I've deglobbed the CPU and desoldered the ROM and incog had clipped off all the wiring, so maybe something isn't connected that needs to be.

If we can't find out from someone who owns one, it'll probably be easier for me to put scans of the front and back of the PCB into GIMP and follow the traces that way.

15 new dumps!
thx to the financial help of Tauwasser and Buddybenj, i could buy these 15 previously undumped US games for the Leapster!

With this batch, we got some more informations:
"500-01168 - Spongebob Squarepants - Saves the Day (US)" is identical to the already dumped "500-11002 - Spongebob Squarepants - Saves the Day (US)"...why did they rerelease this game under a new ID??

"500-12350-A - Letterpillar (US)" is the V1.1 REV of the game! (you will find the header inside the dump) --> i have a V1.0 here too, will get released soon! So we know that there exist definitely different revisions of some of the games!


as with all other Leapster dumps! these roms contain alot of SWF files, which can get extracted with different tools, if you want...

would be great if the games get added to MAME.
Credits would be: TeamEurope, Tauwasser and Buddybenj

Is there a list of VHS-based systems and their titles anywhere? MESS "to be dumped" list has Captain Power (the full name is Mattel Captain Power XT-7, I think), Tiger BattleVision, View-Master Interactive Vision, Worlds Of Wonder Action Max and Bandai Video Challenger systems & their titles listed as secured by you. There's also Bandai Televikko system (with a few VHS tapes digitized somehow) and VTech VideoSmarts (which was apparently the very first VHS console). Are there any others? Was there a prototype of the infamous Axlon Control-Vision aka NEMO?

There's also a weird 8-track audiotape-based console - Milton Bradley OMNI Entertainment System. Any other audiotape-based ones?

I'm not aware of any comprehensive list of VHS based systems. I hadn't even heard of some of the ones you mentioned. I might try to buy some of those. (I doubt I'll find a NEMO prototype, though some of the games did eventually come out on the Sega CD.)

By the way, I did my buy a new VCR, this time from someone who actually knows how to test and repair them. So, hopefully I can actually get some decent captures soon.
