I haven't had the time to make updates, but like I said in the other topic, I've beaten Brain Lord on SNES and Akumajou Special: Boku Dracula-kun on my AV Famicom. Brain Lord never got any tougher than that second dungeon, in my opinion, not in terms of puzzles or in platforming and combat. Even though it's a totally different kind of game, Dracula-kun gave me TwinBee 3 vibes, in that it's a later Famicom/NES release from Konami but clearly was more of a B-tier project for them, not pushing the hardware in any impressive ways like they were with other titles, but still showing off some creative silliness in a simple, fun game. I really love how the first stage of Dracula-kun is basically a chibi-fied tour of the first Castlevania.
Anyway, not sure what I'll sink time into next, but I did briefly try out a Donkey Kong cart I recently bought on my Super Game Boy 2. I've been reading old Nintendo Power issues from around when this came out, and it got me interested in playing it and the subsequent Mario vs. Donkey Kong series that was inspired by it (at least until they turned into Lemmings clones, from what I've heard). The portability of handheld games is a big plus for me, so I've actually barely ever used my US Super Game Boy or Super Game Boy 2, but Donkey Kong takes advantage of the Super Game Boy so nicely that I think it'd be hard to make myself play through it on my SP or what have you.
