Two New Homebrew LCD Games (Game & Watch)

Recommended Posts

Montrose.is/games has long been obsessed with static-screen (e.g. VFD and LCD) games. We had done several static-style "simulations" before and even been involved in some physical reproductions. When MAME started to offer broader support for the TMS1000 and the SM51X based handhelds, we knew we had to do something for real. Many months and tweaks later, we think the games are ready to face the homebrew audience of record.That's AtariAge of course! ;-)

 

Both are written in assembly for the Sharp SM510, the 4-bit (4!) microcontroller that powered the earliest Game & Watch titles. We used the more basic chip because we wanted the games' "release dates" to coincide with the transition between the wide screen and dual screen series ('82-83). Using the SM510 meant that we were limited to 2K of ROM and didn't have the dedicated melody chip that would come later. Instead of melody chip sound, we modulate the SM510's 4096kHZ oscillator in real-time as needed.

 

We ended up writing our own (crappy) assembler that outputs MAME compatible ROMs. The art specifications were also mostly driven by the need to be compatible with MAME. MAME uses SVGs for the actual LCD segments. kittyhawk decided to run with that and future proof the games by doing everything with vectors. For the under and overlays, we had to rasterize them at the resolution MAME (currently) expects, but we've included the original vectors in our zips.

 

We also ported the MAME bytecode interpreter to WASM so that we could produce dedicated in-browser emulators for both games. We actually did this before writing the games, and it ended up being extremely helpful in understanding the platform which is kind of a fascinating combination of 60's and 80's era computing. With 128 bytes of RAM, a Harvard architecture, and a memory mapped display, the SM510 kind of feels like a 2600, the NES, and a mainframe had a handheld baby.

 

BRIDE

Bride is kind of our attempt at an idealized Game & Watch game combining elements of our favorite titles and adding a strategic element not often present in Game & Watch games. Besides the classic "this while that" formula of catching flowers while avoiding rivals, you also have to decide when to end your game as you can only bank your points when you actually get hitched.

SQUEEZE (NFSW)

We've always felt that the Game & Watch deserved a better Simon clone than Flagman. Squeeze imagines an attempt to right that by revisiting the concept with a dual screen version that also returns to the Game & Watch's roots by being an adult novelty. It's also our excuse to get in the ring with Ralph Baer and to take his "'Touch Me' but aesthetically pleasing" idea to its logical conclusion. We're especially proud of having a mode that allows for a programmable sequence, allowing multiplayer play.

 

[edit] If you use the MAME version please note that the keys you need to use/map are UP and RIGHT not LEFT and RIGHT as you'd expect (see manual).

Bride is kind of really cool and a really unique idea, but Squeeze should have a little more variety.

 

Thanks so much for taking the time to play! We really appreciate it.

 

I don't want to promise anything, but I do have a bit of ROM left on Squeeze. Is there a particular Simon mode you have in mind or are you thinking of a more basic change?

I just thought, that if there are boobs, maybe the girl, with her legs up, covering her magic place with her hand, using her butt would add two extra possibilities. :D

Ha! I see. So more DP than just plain DS. Maybe if we continue the series on a beefier platform. Squeeze on NES ("Now You're Playing With Power!") or... of course... Super Squeeze.

These are just awesome, to see people going the lengths like this they deserve more coverage if you don't mind me putting on my site with a post back to here, I am sure Albert will be ok with it?

Thanks! Obviously, we can't speak for anyone else but in terms of us: please post however and wherever you'd like. The love of these machines needs to be spread. :)
