Bomberman Selection Korean selected for a Game Boy Color re-release?

Hudson, a now defunct videogame developer best known for their Bomberman and Mario Party spin-offs, and least known by their Same Game series of games released a few compilations covering and combining their past titles into a single game. Why is this interesting? Well, because one of compilations is probably one of the most obscure re-releases of a videogame since it is more of a downgrade than the usual instance where game developers add more features. While they do just that, they actually remove an entire game, and ultimately select the lesser-great versions of one of the included games in the process. This hasty decision makes it an almost completely pointless release (or re-release?) of an already existing compilation in a very short time apart from the original, Bomberman Collection.

First, let's start off by explaining the history of the Game Boy Bomberman games. Bomber Boy was originally released on 08/31/90 for the Japanese market, sometime in 1991 for the rest of Asia, later as Atomic Punk for the US in October 1991, and Europe received the game titled Dynablaster in 1991.

Bomber Boy is your standard Bomberman Game where you move on a birds' eye grid, place a bomb near stationary structures and moving enemies to blow them up retreiving powerups such as a higher blast radius, remote control detonators for button controlled explosions, bomb kicks, skull viruses that can either hinder the players progress by inverting their controls, disabling their ability to lay bombs, impeding their movement making them vulnerable and other effects, or causing them to speed up. In rare cases this could actually provide an advantage to the infected player. Be ware! touching other players will transmit the effects to them, offering the multiplayer battles an insane turn in either direction for all players. A port of the original Bomberman for the NES was included for good measure and offers passwords and the ability continue after a game over. The highlight of the Bomberman games was the local multiplayer deathmatches which was only achieved via the erroneous, timing sensitive Game Boy link cable. Good luck!

Later releases spanning different consoles offered slightly different gameplay modes, but overall the core gameplay remained the same; the Sega Saturn version even offered new mechanics such as interactive stage effects ranging from spotlights that only showed the players position and a very small window around them, affected controls by pressing switches by walking over the ground are just a few examples. The Sega Saturn version featured animal companions for various protections and abilities, and the now-defunct Netlink service which allowed dial-up competitive deathmatches!

Bomberman GB2 was released for the Game Boy in 1994 initially only offering the ability to play as the white bomber hero, then when Hudson partnered with Nintendo, they added Wario to mix. Bomberman GB2 is curious because it was the first game to use the Super Game Boy's internal SOUND functions for enhanced explosion sound effects and a few others in certain situations, and the game also setup and allowed for up to four local players to compete with each other without needing a Game Boy link cable as long as they had access to a SNES Multitap accessory. The drawback is the small screen area and that all players always had to be visible on screen at all times, something that the console versions worked around by using smaller sprites and landscapes. Bomberman Pocket also supported both features, which was unfortunate a rarity at best when it came to other games.

Pocket Bomberman was originally released in monochrome in Europe and it did not offer any other Super Game Boy features aside from palettes and a few display borders that changed based on game modes, no enhanced internal SOUND functions or multiplayer battles. Later, it was released for the Game Boy Color with no upgrades aside from the expanded palette for the system. Curiously, the original European version does actually load a pre-defined palette scheme if played using a Game Boy Color. Only games released in which Nintendo either published, developed directly or as a second party received special palettes if a button was not pressed when booting up.

Bomberman 3 was the last entry in the series and is a Japanese exclusive and was offered in standard and interestingly as a Nintendo Power GB Memory flash cart title. The game is exactly as you would expect from a Bomberman title without the multiplayer staple, and strangely Hudson forgot to add the Super Game Boy SOUND effects this time around. Interestingly, the game does setup MLT_REQ 03 signifying it does internally support up to four players via aforementioned SNES multitap and controllers, so, it was an early idea? Just for clarification, the original NES Bomberman and all sequential ports including the Game Boy Advance Classic NES Series also plays a DPCM explosion sound sample in their various emulated forms. Time trials and score attack and hidden boss attack modes are offered in this version, I guess as a bonus. In this installment you acquire powerups by buying them in shops. Bomberman 3 is a solid game that does have several missing features and feels very incomplete overall unpolished in contrast to the earlier games. Was it rushed? No clue but I am curious about the omissions.

Hudson released two Bomberman compilations for the Game Boy, and in a metallic tin case (hope I won't be afflicted with tetanus from handling my very slightly rusty Bomberman Collection videogame on extremely rare occasions), which was not really ideal unless you keep it on your shelf forever. The compilation includes Bomber boy, Bomberman GB and Bomberman GB 2 with no changes made except that it uses the memory mapper MCB1M. Here is an oversimplified explanation: the chip allows multiple banks of games to be stored in and swapped out of the consoles RAM than normally accessible by the 32kb and 64kb limitations. Bomberman Selection also relies on the same mapper.

Bomberman Selection is where things take a strange turn. For some inexplicable reason Hudson not only released Bomberman Collection in Korea only, they decided to remove Bomberman GB2 and downgrade Bomberman GB to the original version not including Wario, and lastly they released the game so it was only compatible with the Game Boy Color which is ridiculous because all of the games were not designed for the Game Boy Color at all. This was unnecessary and likely hurt sales of this collection. Interestingly, Super Game Boy borders and all other assets were deleted from the games that originally supported them leaving the space where they would have been completely empty and not used for additional space. This extra space was not used to map out the new palette assignment banks for the Game Boy Color, as you would imagine or expect making this more of a curiosity at best. The game select menu does contain its original Super Game Boy assets but the code to access and load them was removed and changed deliberately instead of actually deleting the files as they did with the games themselves. I actually took the time to restore the leftover menu Super Game Boy support. Here is my quote from Twitter:

"https://gamehacking.org/vb/forum/video-game-hacking-and-development/hacker-threads/13028-nensondubois-codes/page65#post207018 - Bomberman Selection Korea actually does contain the leftover Super Game Boy prg from Bomberman Selection, which was released earlier. Video soon. The SGB from Bomberman GB2 actually was removed; SOUND, border, PAL_SET does not exist in the GBC ROM.

Code is long but I took assembly shortcuts to cut down, which took 3 minutes, plus 22 or so to manually write down. Enable leftover Super Game Boy support from Bomberman Collection. Bomerman GB2 / Wario Blast Featuring Bomberman does not actually load commands after "MLT_REQ 00"

A lot of header information was changed per game. The sound test does work in Bomber Boy as well in DMG, SGB and CGB modes."

So, in conclusion, Bomberman Selection is a novelty more than just a curiosity at this point with all the strange development choices.
