I'm still wondering what the heck that logo actually belongs to; I've seen it in several Nice Code plug-n-plays, with no further identification of the company any time it's shown.
The letters in that particular sprite are much more clearly "TWLS" (I'd thought it was perhaps "TWCS" or "TWTS" in the past), but I still haven't the slightest clue what that actually stands for.
Also, taizou, your links are labeled backwards. The "NES" one is the BIN, and vice versa.
