Atari kernel vs Android

So tonight I split some time between writing code for a couple of new items in Robo-Ninja (the laser gun, and the "wall slip", where you can cling to and slowly slide down a wall), and working on trying to jam pack everything into my Atari "kernel" (the name they call the core display loop on atari games).

The contrast between the two was hilarious. I'm going slightly over my cycle count on my Atari kernel -- once I added code for displaying missiles and background, I'm taking too much time per scanline.  But I don't really want to cut any functionality out, so I've been tweaking and optimizing, trying to pare down an instruction here, an instruction there. My brain is now tired. I managed to squeeze it down to ALMOST small enough. Squeezing the rest is going to be pretty difficult.

Then back to Robo-Ninja. Writing in Java (instead of 6502 assembly!), not really worrying about performance unless I do something stupid. I can waste lines like crazy, and it doesn't really matter at all.

Weird.

Retrospex 32 Review

RetrospexInternational recently sent me a couple units of their new handheld device, the Retrospex 32, a new dedicated GameboyAdvance emulator handheld.  To make the unit playable out of the box, they pre-loaded a handful of homebrew games, including Anguna, which is why they were kind enough to send me 2 of the units to play with.  I was pretty excited to get my hands on the device and try it (I loved my old GBA micro with a good flash cart!), and see Anguna running on it. So here's my thoughts after playing with it.



Their website lists the Retrospex 32 for £59.99, which is around $100 USD. It seems like it's marketed toward people into retro-gaming (which makes sense for a dedicated GBA emulator device). At that price, with that target market, and such a limited set of functionality (why not make it a multi-machine emulator, and emulate all the old consoles?), it would hopefully do a really good job of it.

The short version of my review: it doesn't. It has one job (emula…

Making the game fun

The real trick for Spacey McRacey (as I'm calling it now) is going to be making it fun.  And that's what I'm rather unsure about at this point.

I have a game design that basically works. The technical issues are mostly sorted out, I just need to get a few more implemented before I can seriously play test it.

But fun? It's hard to know if it's actually going to be any fun to play.  With a 4-player party-style game, it's seems like it might be hard to hit that fine line where everyone is close and competing, where everything feels exciting and tense, as opposed to tedious and boring.  And despite envisioning my game as fun, it might just be boring to play.

Some of that comes down to tweaking it. Tweaking the speeds, difficulties, etc, will make a difference. (If it's too easy to shoot people from behind, then it will be nearly impossible to hold a lead for very long, which could ruin it and make it no fun. If it's too hard to kill the guy in front, it wil…

Killer Queen

So at PRGE, I played an arcade game that just left me amazed.  Killer Queen.

It's a 10-player game. You have 2 cabinets linked together, and 5 players huddled on each one. Each one is a team of 5 people, working together to play a simple one-screen 2d platformer.  But what made it work was the high quality game design.

First, the game is relatively simple, yet there is a lot going on at once.  One player plays the queen, the most important and powerful character on the team. The others start as workers, but can become warriors who can fly around and attack in a very joust-like flappy contest of height.  The real trick is that there are three completely different ways to win: either collect a bunch of berries and bring them back to your base, or ride a REALLY SLOW snail across the screen (while other people try to kill you, and you hope your team protects you), or kill the enemy queen 3 times.  There's some other things going on as well (using berries to upgrade, capturing upgr…
