Submission #8646: BlackWinnerYoshi & Spikestuff's GB 4-in-1 Fun Pak: Chess "2 Gameboys" in 00:15.02

Improved by 1 frame by Spikestuff.

MobyGames: 4-in-1 Fun Pak combines four board games to play against the CPU or a fellow gamer. The include titles are Chess, Checkers, Reversi and Backgammon. Each game features a number of different difficulty settings (1 being the easiest, 6 being the hardest), with simple black and white visuals and a challenging CPU opponent to take on. Multiplayer is available, either using the same Game Boy between two players or using the system link option to play with two Game Boys.

This TAS completes Chess as quickly as possible by using two human players and checkmating White with the fool's mate.

The biggest problem here would be plagiarism, but it turns out that Gambatte with AGB completes this 20 frames slower: 13.8 frames is the GBA-GBC switch, which GBhawk doesn't emulate but Gambatte does (it really just does nothing for that many frames); 6.2 frames is probably increased accuracy? Of game emulation itself, or link emulation? Who knows, but I have made two videos that attempt verifying that... well, the rerecord count is accurate. The hashes listed in the videos don't match because the movies I uploaded had their headers tweaked slightly for consistency, and I also used TorrentZip for that as well. Oops.

Gambatte is 13.8 frames behind GBhawk because of GBA-GBC switch emulation.

After selecting two Game Boys with the first Game Boy (bro what :skull:), Chess etc., I just do the moves like displayed on that Wikipedia image. In Gambatte, the other 6.2 frames go somewhere during the game, I guess.

Possible improvements: probably none, unless I screwed up something in Gambatte, I definitely still want to prioritise this core over GBhawk (not that Alyosha is gonna verify this anytime soon... who knows. Would SameBoy do it any differently?)

no of course I messed it up lmao. well, I guess it means that previous run was suboptimal as well, since the time without GBA-GBC switch emulation is 00:14.68. or 00:14.58?

Suggested screenshots (according to the frame counter in BizHawk): will be here once I encode this thing maybe near the checkmate?

nymx: Claiming for judging.

nymx: Updating with the BK2 mentioned by Spikestuff

nymx: Alright...looks like I have enough information to finalize this submission. First off, this was a learning experience on how to set this up...now that I have that out of the way, let's judge!

I think the confusing part of this was separating the work that BlackWinnerYoshi did from what Spikestuff did to improve this run by one frame. With Spikestuff's contribution, it appears now to separate it from what OtakuTAS did and thus shouldn't be problem for plagiarism. I'm leaving the authors as is.

As for the run, my background with chess agrees with the strategy. Unlike other runs on this site, the game operates more solidly and doesn't have any interesting glitches to break the game with. Good job.

Accepting.
