Neotris, a new game for Neo Geo (tetris-like with 4P mode)

[totologic]

Hi guys.

I am here to present to you the Neotris project. It started 1 year ago, when I started programming for Neo Geo.

In a few words, Neotris is a tetris-like with solo 1P, versus 2P and battle 4P modes. The 4P works with a home made multitap.

The game is in beta version, 98% completed and it is almost ready for physical production (but it will wait the end of the Covid-19 crisis for that ).

A demo video is available here: Neotris Attract Mode and Solo play

The inserts in US and JP version:

Today the beta version is available for free downloading. ROM can be found for MAME, Darksoft Multi and NeoSD.

Links and instructions are here: https://www.chipsonsteroids.com/

All feedbacks are welcome. The final version of Neotris will also be in free downloading.

At last, you can support the project : https://en.tipeee.com/chipsonsteroids

Have fun !

I was hoping maybe I could make a dedicated conversion cart for this bit it seems the V-ROMs are too big.

How do I get this onto my NeoSD, would love to give it a try on my home console. Do I just copy to the SD cart?

Thanks

Oh man this looks really great; looking forward to the physical release. Would definitely play with friends.

How do you mean too big?
Should fit on any PROG board which can use 4 VRAM slots?
PROGBK1 or similar

Or is it not possible to use m27c322 for vroms(havent tried)

Any plan for an official MVS release btw?
I like to support homebrew (like ngdevteam), but have no interest in AES.

Sadly, the Covid-19 crisis has frozen all the plans for physical production.

 

[buffi]

Oh shit, that's unfortunate

Well, I'll keep my hopes up for a physical release some time in the future. Next year is also a good year to buy stuff!

You can also support the free version with a donation. Be sure it will help to improve the game.

Well, it's not much but sent you a small tip at least

The game is free for downloading and playing, but don't forget that the game is not open source and it is protected by intellectual property.

Making a convert for your own purpose is OK. But I expect people will not try make convert to sell them, as it is absolutly not the aim.

 

[totologic]

Thank you ! Your support is really appreciatd

 

[Dache]

That's great work, congrats!

Can you tell us more about the 4P multitap? How are you handling four player's worth of inputs on the NG's 2 ports, what was the process like to figure it out? That's a whole level above just making the game!

Of course not!

I've also left you a tip. Looking forward to the final release.

I plan to release the electronic diagram for the multitap.

That is really simple, the multitap uses the 2 ports of the Neo Geo, 2 controllers being multiplexed on each port. I use the same principles as the Majhong controller, the pins OUT 1 and 2 are switched on/off to select the relevant inputs.
