I am thinking about programming a fighting game for the Odyssey 2. Would you guys like one, and if so, should it be 2 players or 1 vs. computer? I finished Insecticide, a fighting game using insects, for the Virtual Boy, and would like to "port" it to the Odyssey 2. What say you?

can you make it so there is an option for the player to play against the computer and also an options for player 1 vs. player 2 ?

I guess I could do that. Right now I'm working on the player select screen. I'm finding it really hard to draw insects using 8x8 pixels. Right now I've just got Gi-Ant and Meleedy-bug in the game. I'm going to add Behe-moth and one more for a total of four fighters, like Title Match Pro Wrestling for the Atari 2600.

The select fighter screen is mostly done. I have to think of one more insect to carry over from the Virtual Boy version, or create a new insect fighter with a punny name. I can't do Slaying Mantis because the name is too long. I'd like to keep the code simple as possible, which is why I'm using 8x8 characters. Anyway, press left or right to change a fighter. I was going to make this 4k, and have the first 2k be just the fighter selection process and the other 2k be the actual fighting game.

a fighting game would be really awesome..i would be completely happy with just a 1p mode it this saved capacity for the actual.game.

Well, the select fighter part of the game took less space than I thought it would. I am going to add a title screen, though, but still. I went back through some game I made I remember that had a bee in it, so I used that sprite here and made it Rumble-Bee. I have an idea to add a second sprite for the hands of all the insects be the same if they punch, a single punching sprite. I would like to put the name of the game on the title screen, so I guess I'll call it Insecticide as well. This is going well for just a single day of programming!

Yes, this is good because the Odyssey² / Videopac does not have a fighting game ... not even a boxing game.
So I think this will be very nice that you are filling a spot in the library that did not really ever exist.

Fun! Do you have some video of Virtual Boy version?
It just reminds me a strategy game I used (and loved) to
play back in the days.

timdu · June 05, 2016, 03:23:34 PM

I thought I remembered a BOXING game for the Odyssey² being worked on at some point...

Yes - our friend Rafael was working on one called "BACK TO THE RING" in 2012

Rafael - what are you plans with this?

Chris! · June 05, 2016, 03:49:24 PM

I finally got a (primitive) title screen working on real hardware. This took about 10 minutes to code, then I discovered it wasn't working on a real O2, so the next 20 minutes was trying to figure out why, moving the code around, etc.

Chris! · June 05, 2016, 04:46:14 PM

Well, I guess this means I don't have to work on this any more.

I can´t see why.
Odyssey have a card game (Blackjack) it doesn´t mean you can´t work another card game
(Poker, for instance), since it´s totally diferent experience.

OK, but I spent the last hour trying to duplicate the fighter select menu for player 2, but I just couldn't do it, so it will have to be a 1 player vs. the computer game.

Virtual Boy release?

Chris! · June 06, 2016, 10:59:04 PM

Yes, I programmed a version of Insecticide for the Virtual Boy. They're supposed to be releasing it, but the guy who does it apparently keeps forgetting about it so it hasn't been released yet.

As for this version, I seem to keep having trouble. The trouble is, player 1 picks a bug and presses fire. Player 2 however, when the choices scroll by, I want player 1's choice to not be visible and instead scroll to the next version. I have this code in left and right's scrolling:

Code Select


	mov r1,#fighternumber
	movx a,@r1
	add a,#001h	
	movx @r1,a	

	mov r0,#fighter1number
	mov a,@r0		
	mov r7,a

And that's it. I want to test fighter1number and if it is the same as fighternumber, then add (or subtract) 1 to fighternumber. Fighternumber is the fighter currently on screen, while fighter1number is (supposed to be) the fighter player 1 picked. But I'm having trouble with it. If you download the code, the problems start at lines 710 and 886. I don't know what to do here.
