[Coding competition 2014] BOoM by ichigobankai and Vingazole

*MOD* Added version 1.1 (April 5)

BOoM, based on a well known battle game (bomberman)
You need a homemade multitap to play it correctly with up to 3 friends on Hardware.
No emulator can run properly the game (you control all players at the same time...)

My very first program in C, an dmy first ever program for our dear Master System.
I've used z88dk, but the project will slightly move to SDCC which seems to be much much more better & optimized than z88dk.
My friend Vingazole converts critical things into asm (because z88 is slow & not optimized !)

Unfortunately, it's unfinished, i've only started this 4 weeks ago.
Graphics ripped from few bomberman games, edited to fit the console limits.

With this multitap, I've got other multiplayers game in Mind now ^^

Original Multitap code/scheme by Furrtek.

What can I say... nice graphics, classic gameplay and an interesting use of custom hardware. ;)

I hope this game gets finished. I really like bomber man games!

So much potential in it, and I love the multitap design.
Just a word of warning - it can and will ruin Mega Drive pads. Raising ground of a logic chip is very very unhealthy when other signals go below it !

Thanks guys ;)

I'll add random generated playfield (destructable blocs) next week I think,
I've also imagined a "level select" (with thematic playfields like green hill, monster land....) but before adding select stage/music etc. the project will move to SDCC.

I found an interesting comparison between z88dk and SDCC : http://www.cpcmania.com/Docs/Programming/SDCC_vs_z88dk_Comparing_size_and_speed....

Thanks TmEE for the warning !

Very nice graphics. Gameplay seems smooth, as far as I can judge without a multitap.

I wasn't able to run it in Emulicious at all, though, and it crashed in KegaFusion after a minute or so.

How hard would be to release a 2 player version using the standart controller ports?

On a scale of 1 to 10, I'd say 0 ;)

So I'm assuming I can't use a Mega Drive multitap to play this.

Yes...you need the specific multitap made for it.

I've added/fixed chained explosions, fixed some little things (animated death / results). I'll send a new version when i'll add the random/destructible playfield blocs.

Well, then. Could you release along with the original version?
that way i could test on a real hardware.

I hacked the last ROM that ichigobankai sent me, as I don't have the source code of the game...

I'm pretty sure that's only megadrive pads used with this specific multitap which is dangerous for them.

TmEE will confirm that (I hope ^^)

All pads that have a chip in them will suffer. SMS pads have nothing so it works on them. Same thing with Sega SC-3000. MD pads will hate being connected to it or any other pads with chips as they use same kind of logic to select pads ("remove" ground). The ESD pretection diodes will go into overdrive and eventually burn out with the chip.

White player starts powered up but not the black player!

It's a cool base to have this running. Would be lovely to see the game finished with bricks and some items.

Yes, I've initialized the white player with a x3 long flame (instead of x1) just to "test".
I think random arena with breakable blocs/items will be ready this week ;)

Thank you!!

Just a small issue I have with the controls:
when you are facing a block in your left for instance, you have to release the left button and than press the up/down to move your caracter. I think will be much more intuitive if you allow the up/down buttons even if the left button is pressed. Other than that, is really nice to see a Bomber Man game on the Master System

Items & pickup done.
Need to fix some tiny bugs, but can be played.
No more update now, until the project have been moved to SDCC.

This is a really nice port, palette choice is very accurate I think.

Just wanted to tell I have added emulation of that homemade multitap in Genesis Plus GX using the schematic you provided:
https://github.com/ekeeke/Genesis-Plus-GX/commit/df6dbe855ad4689c5fb6d06ea9a5271...

Tested last version on Wii with 2 other casual players, the fun is definitively still there ;-)

Thanks Eke, I must try this on my wii !

While my friend Vingazole look at SDCC, I've started to draw some cover art.

Edit. Cover art finished ;)

Some little news !

Vingazole have nearly finished to set up SDCC.
Seems to work very well.

I've started to organise datas into 16ko banks, make some arenas with Tiled editor (a great tilemap editor), edit some new arenas GFX.

Receive Multitap prototypes (drawn with eagle few weeks ago)

Board game pcb routed, will be sent to fab to make protos soon .

I've found them on http://www.te.com/en/home.html

Unfortunately i will not use them on the boards because they are very expensive (~5$ / each), even on Chinese market like taobao.

Those ones are free samples ;)

This MasterTap is an amazing homebrew piece!! BOoM is a homebrew game created to make use of this MasterTap (what could happen if we throw both BOoM and a MasterTap in a Time Machine back in the early 90s? LOL), but can be possible to get some SMS games, like California Games for example, and hack them to have suporte to this piece? As California Games can be played to 8 players (alternating), two MasterTaps can be used, one for each controller port.

I have some questions... It's possible to make the game recognize if the MasteTap is pluged or not on SMS to enable/disable the support? If yes, there's some plan to update BOoM to have this feature? With this, the game can be played with and without the MasterTap.

Can you add options for Mega Drive 4 player multitap (official Sega version) and the EA 4 Way Play?

Technically, the Mega Drive multitap is compatible with the SMS hardware (except on Japanese consoles), but it requires specific code in the game to support it. It would require a bit of investigation as to what the multitap does when an SMS pad is inserted but most likely works as well as using an SMS pad in a Mega Drive game ever does.

So, who wants to offer to donate a multitap to the developers so they can code support for it?
