GBX v1.0 important notice!

posted by taizou @ 2018-03-26 22:18:26 Other Stuff

Unfortunately, and perhaps inevitably, I fucked up a small part of the initial version of the GBX v1.0 spec - the text mistakenly specified all numbers should be little-endian, when the examples (and my emulator, and the ROMs I released) all use big-endian, which was my intent from the start.

I've fixed this and you can find the updated version here. Note that I'm not considering this a version update (because the old version was purely a mistake and contradicted its own examples in any case) so the version number 1.0 is retained.

Makon Crapstravaganza 2018 Part 2

posted by taizou @ 2018-03-21 00:27:04 Dumps

HEAVEN OR HELL
LET'S ROCK

YEAH THERE'S MORE. Once again these dumps will currently only work in hhugboy v1.2.5 or later, but v1.2.6 is recommended since it fixes a save bug. GBX versions will work automatically, raw dumps require "NT (Makon) new" compatibility mode to be manually selected.

Digimon 02 4

This is the English version of Shuma Baolong 02 4 from the last batch of dumps. It's... in English! cool.

Honestly this is probably one of Makon's better games, for what that's worth - okay you might fall through the floor sometimes, but at least it's mostly controllable and the level design isn't too punishing. Even the sprites are pretty cute!

Pokémon Diamond (Special Pikachu Edition)

You may already know "Pokémon Diamond" as the bootleg English translation of Telefang: Power Version. This is not that game! This is the "Special Pikachu Edition", a rehash of Super Mario Special 3, with Pikachu and a better colour palette.

Unfortunately, this version also omits the map screen, instead starting you on a level heavy on precision platforming, rendered near-impossible by the poor controls. If you manage to make it through that level via some miracle and/or savestates... there's a block, and you hit it, and an item comes out, and nothing happens. So you can't proceed past level 1. This level was similarly broken in Super Mario Special 3, but given that all levels were selectable from the start, you could at least skip it. Here, they aren't, and you can't!

Now, I dumped a Li Cheng release of this game a while back as Shuma Baobei: Hai Zhi Shen, and for once the Li Cheng version is actually the superior one, because... they fixed that bug! So if you want to actually play the game, that version is the way to go.

Pokemon Jade (Special Pikachu Edition)

You may already know "Pokémon Jade" as the bootleg English translation of Telefang: Speed Version. This is not that game! This is the "Special Pikachu Edition", a rehash of Sonic Adventure 7/8, with Pikachu and a better colour palette

...hold on, haven't we been here before? Yes, Makon/NT released their own Pokémon Diamond and Jade versions suspiciously close together, almost as if they were trying to cash in on the other Pokémon Diamond and Jade versions...

This game even shares a few more similarities with Diamond: it starts you on by far the hardest level, with lots of precision platforming (one jump is apparently impossible unless you lure one of the Porygons from further back in the stage and bounce off it), and... once again, it's fucking broken and you can't pass stage 1. This time, it just crashes when you touch the sign at the end.

If you want to see the rest of the levels, you can cheat your way around it by setting memory address C27D to a number between 01 and 04 for levels 2 to 5. In hhugboy's simple cheat format that would be C27D=XX or GameShark/Action Replay Pro 01XX7DC2, with XX replaced by the level ID you want to skip to. This will actually work on a real cart with Action Replay, as long as you only flip the switch on and off on the 'start' screen.

Interestingly, this wouldn't be the only time Makon rehashed their Sonic games in Pokémon form. Pokémon Adventure, also known as Pokémon Gold Version 2, uses the same Sonic engine and the same Pikachu sprite as Jade, but features redesigned levels which are quite a bit more forgiving than those found here. Overall Adventure feels like a somewhat-refined iteration on Jade, but... it's dated 2000, a year earlier than Jade's 2001. So Jade is both broken and a step backwards.

Makon Crapstravaganza 2018 Part 1

posted by taizou @ 2018-03-11 23:56:59 Dumps

So, now I have a finalised GBX format spec, and an emulator supporting the new format, I can finally get to releasing some GBX ROMs! And what better way to herald the arrival of a fancy new ROM format than, uh, *shuffles papers*, seven Makon games?

That's right! Makon Soft Studios, makers of many highly-regarded classics, kept pumping em out all the way through the GBC era. These games do show some progression from their earlier stuff - they make WAY better use of colour, and sometimes even the music is more tolerable. Unfortunately they still suffer from too many control issues to be really enjoyable to play in any capacity.

The publisher here still appears to be NT/Ka Sheng/Ka Sing/卡聖, but they've switched to a new mapper with half bankswitching functionality (used by these Makon games) and an entirely new mechanism for selecting multicart games (which I've yet to figure out, so no multicart dumps just yet).

These games will only run in hhugboy v1.2.5 or later (although I recommend you use 1.2.6 or later since that fixes a save bug affecting at least one of these games). The GBX versions will run automatically, the raw .gbc format ones require you to manually select "NT (Makon) new" compatibility mode.

Pokémon: Mewtwo Strikes Back

First up! Mewtwo Strikes Back is a platform game more or less based on the superior unlicensed game "Pocket Monster" for Mega Drive and SNES. And with intro text attempting to tie it into the movie of the same name, with which it otherwise has no connection. Previously I dumped a Li Cheng hack of the Chinese version of this game, but now here's the English Makon original!

HEALTH WARNING!! Pikachu's electric attack in this game (A button) causes one colour in the background to flash rapidly between yellow and red, in a manner reminiscent of the infamous Pokémon episode Dennō Senshi Porygon. The effect isn't too bad when viewed on a Game Boy, but especially in later stages it can appear quite intense when displayed at a larger size on a modern backlit screen. Therefore please use caution when playing this game if you are sensitive to flashing/strobe effects!

Digimon Pocket

Later, Makon revisited Mewtwo Strikes Back, as they so often did, rejigging it into a completely "new" game. So the stage order is changed and it's now about Digimon instead of Pokemon. But one actually useful addition they made here is a save feature! The game now automatically saves after every stage you clear, meaning you no longer have to complete the whole damn thing in one sitting. This makes reaching the ending a lot easier... except they took the ending out.

HEALTH WARNING!! Since this game is basically just Mewtwo Strikes Back, the same red/yellow flashing effect is present here too.

Digimon 2

Another Digimon platform game, but this time they came up with something entirely new instead of rehashing a previous game! Probably for the last time! This one adds a mechanic whereby you have to fill up your "MP" bar by collecting items before being allowed to complete the level.

Thanks to Robyn for dumping this one an extremely long time ago!

Shuma Baolong 02 4 (數碼暴龍02 4)

Another Digimon game based on the Digimon 2 engine; I think this one may add more levels, although I haven't played through the entire thing to check. This is the Chinese version, I have an English version in my possession too and will hopefully be releasing that soon.

Note that this one was already dumped quite a while ago, and is in GoodGBX - my new dump matches it 1:1 so you can consider this a verification rather than a completely new thing (since a lot of unlicensed dumps in GoodGBX are of pretty dubious provenance)

Raw: Shuma Baolong 02 4 (Unl) [C] [Raw].zip

Harry Potter 3

That Digimon engine makes another appearance, but the hero this time is equally-popular bootleg target Harry Potter, in a game trying to pass itself off as a tie-in to Prisoner of Azkaban (the book, specifically).

Unfortunately... this one is broken. On the real cartridge as well as in emulation, it crashes halfway through level 1. It should be possible to hack the save file to access later levels, however.

Street Fighter Zero 4 / Jieba Tianwang 4 (街霸天王4)

Tired of platform games yet? Good, because here's something completely different. It's a fighting game, based on Street Fighter Zero/Alpha 3! It's also a mess!

I'm not entirely sure if this one is a "true" Makon production, since it seems to have more links to Sachen than their usual work; there are elements of Sachen GBC games here, most obviously the COMPLETELY out-of-place Jurassic Boy 2 theme on the title screen. But it was certainly published through the same routes as Makon's games.

Capcom vs SNK: Millennium Fight 2001

And finally! This is another fighting game, and another original release of a game I've previously dumped in Li Cheng-hacked form. Most notably, this version has a bunch of extra frames in the intro - which is interesting (to me) because they used a high-colour trick seldom used on the GBC, switching palettes on the fly as lines are drawn, to circumvent the system's usual palette restrictions.

And as a game... it's also kind of a mess, but at least it has, like, four voice samples now! It is pretty different to Street Fighter Zero 4, to their credit, they didn't just take the old game and slap new characters in it.

Thanks to Pepper9801 for lending this cart (also an extremely long time ago)!

hhugboy v1.2.6 release!

posted by taizou @ 2018-03-11 12:15:39 hhugboy

This one's a bugfix release - it fixes a long-standing issue in the way RAM banking was implemented in MBC5 for games using 32KB RAM.

Specifically it affected Fengkuang Dafuweng (causing saves to become corrupted if you started a new game then reset before naming your character), as well as one of my upcoming releases.

get it here!
