The ROM daughterboards for the two Leapster 2s had slightly different silkscreening: 20055+003+1004 with a datecode of 0619 and 20055+003+1006 with a datecode of 0652. I dumped both of them and they are quite a bit different; there's a lot less empty space in the 1006 version. The latest date I found in the 1004 file is Aug 30 2005, and in the 1006 file is Oct 21 2005.
Edit: are these Leapster 2s or Leapsters? The datacodes make me think they are too early for Leapster 2s.
I also cleaned up some other dies looking for part numbers. There's no info or logo on the Sensible Soccer die. The Grandstand Game Player just has the part # 1C5738 and ID of 1645, no company name or logo. Skateboarder is a Sunplus QL8041C. The Cube World Block Bash small die is a Winbond SA5623 and the big die is a Sunplus QL6045.
Skannerz has a Winbond SA5621. Radica 20Q has a Sunplus PL6413.
they all seem to be Arcompact baed (ArcTangent 5.1) and follow the same code execution.
At the very least the TV one we have identifies as a 'TV' unit, while these don't specifically say Leapster 2 outside of the 'v2.1' strings. I don't know if there are any real differences?
Skateboarder is going to be interesting to see the ROM for then, to see if this Sunplus is an evolution / rebrand of the Elan ones, or actually something else entirely.
btw, for reference, the Radica Tetris and Arcade Classics you dumped were both PAL, right? While Golden Tee was NTSC?
you'll probably end up with a spare Skateboarder at some point due to a miscommunication with Peter, who asked if it was dumped, not realising you had it but hadn't dumped it, although who knows, maybe there are multiple software revisions on them too. Is this Skateboarder an NTSC or PAL?
