Nine

So I was working on my Game Gear game again today. I designed some new numbers for the score. But something was wrong with the 9 digit. It wasn't put in the game. So I wondered why. I went back to the bmp2tile messages to see if anything had gone wrong. It only read numbers 0-8. 9 was on the end and for some reason didn't get read at all. So I moved it one pixel to the left and tried again. Success.

I don't know why that made a difference though. I used the Century Gothic font to make these numbers. I typed in all 10 digits with the size of 8 pixels. For some reason MS Paint likes to blur text. So I went to Photoshop and smoothed everything out getting rid of the stupid blue and purple shades Paint gave me. This is the result:

I also learned that black is the same as transparent. Which is odd because when I made my first three games, I used a red color for the transparent parts and worked out fine. I guess the proper way is black. So when these numbers get shown on the screen, the background gets shown behind it. I tested to see if the numbers worked right by adding 1 to the score every second. The 9 digit came out as garbage. That's how I discovered something was wrong.

I have been using Emulicious for Game Gear emulation, so I opened up the tile viewer and lo and behold, no 9 had been entered. Later I will test this on a real Game Gear with my Everdrive. I bought an Everdrive a few years ago for my Game Gear when I first tried to program for it. It's funny though, after a few years it still works like a champ and I have no problems with it. The guy who owned it before me must have replaced the capacitors on it, or I must have extremely good luck.

Before this, I went back to work on Chris's Casino for VB and Las Vegas Slot Machine for the INTV. Just a lazy Sunday sitting at my computer working on stuff I don't need to do.

Are those bitmaps copied from ROM into VDP RAM, or whatever it is called on the Game Gear? I'm thinking perhaps your loop ends one iteration too early, i.e. the difference between for (i=0; i<9; i++) and for (i=0; i<=9; i++).
