Since I made an Ants for the Atari 2600 and I’m busy with Ants for the Odyssey^2, I thought to myself, why not make an Ants for the Virtual Boy? So, here’s the beginning. It wasn’t really a very fun game to begin with, more like a programming exercise, but I’d like to make a version of it for every system I know how to make homebrew games on. Since I know a little on how to do the Virtual Boy, I thought I’d do this. Note that this is a beginning, not the final product, and I hope to have stuff like walls and a timer (and if there’s a timer, there should be lives, too) before I finish it. The premise is simple: Touch the ants. To start a game, press A. I know this game doesn’t have to be 512k, so if someone can please tell me how to make the game smaller in size, I forgot how to do that.

But just zipping the ROM would at least shrink the download quite a bit. 7-zip has excellent context menu support to make this super fast.
I don’t have time to try Ants now, but I’m glad you continue to polish your VB (and other console) dev skills! :thumpup:
I’ve run into a little problem: If you get above 99 ants, the counter goes crazy. Is there any way to stop this?

You can use the PrintStr function from Soviet Union 2010 to print numbers over 99.
I use dasi’s posprintf() port. It wouldn’t be hard to cludge another digit into your existing cludge, though…
. . . char ants_str[4]; // Should probably be initialized . . . // TODO: put some range checking here ants_str[0]=(antc/100)+'0'; ants_str[1]=(antc/10)+'0'; ants_str[2]=(antc%10)+'0'; . . .

As with both suggestions, I keep getting an error message that says the following:
“passing arg # of ‘posprintf’ makes pointer from integer without a cast.”
Replace the # with a number from 1-3 and you get my error messages.
You don’t pass the number as the string to be printed, you pass a “formatting string” and the number as an argument.
posprintf(ants_str, "%d", antc);
Or, to limit it to three digits:
posprintf(ants_str, "%03d", antc);
Just search for a printf tutorial.
OK, I tried what you did on the edited post, and I got a number that said 1A0 when it got to 110.

This wouldn’t work. What if ‘antc’ is, for example, 110? Then ‘antc/10’ would be 11.
EDIT: VirtualChris already caught it.
It was just a quick example to point in the right direction. I think printf is the way to go, but here’s the right cludge, for posterity:
. . . char ants_str[4]; // Should probably be initialized . . . // TODO: put some range checking here ants_str[0]=(antc/100)+'0'; ants_str[1]=((antc%100)/10)+'0'; ants_str[2]=((antc%100)%10)+'0'; . . .
