Yes. But it starts to lose followers of this thread.

You can ask help if you have problems with codes: http://atariage.com/forums/forum/51-atari-5200-8-bit-programming/ Someone will help you.

Did you update the system to 6.20 in video?

Sad but true.

Superman would use sewers if no one is watching. I don't think cities will remove sewers anyway.

I went to town and I noted the telephone booths are gone. Who needs public telephones when everybody have smart phones?

If a room would takes only 192 byte uncompressed, it would have 170 rooms in a 32kb and have only 38 byte left for the rest. Not a good idea. I get it. Maybe I should make a simpler game to learn how to make a colecovision game, not to make a complicate game too soon. I noted the ICVGM303 can corrupt data. Is it a glitch or icvgm cannot handle so many sprites/patterns? Here the topic. http://atariage.com/forums/topic/256041-arrgggghhh-video-corruption/ Rockcutter reminds me a gameboy game. It looks nice. Is this game available to download? If I need more tips, I'll ask to the forum. Thanks for this comment.

That reminds me DOOM II.

I made a room editor for my colecovision game. It would be easier to design rooms. With this editor, you can export codes to make the game like this. Just copy and past these codes to your programs. I noted CCI supports only strings with 256 characters. But this is still fine. Instead writing 24 lines of codes just to display in the full screen, just one string will fill up 8 lines. I only need three strings to full the screen. I'm not sure if a colecovision game can handle 200 rooms. Montezuma's revenge has 100 rooms in a 16k cartridge data. A 200 rooms game would take 32k of data. Maybe more with the rest of code to make the game to run.

And virus free.

It could be the origin of the problem if ICVGM gives this message in the first place.

The 3d glasses I ordered came yesterday. I can enjoy any games who support 3d. Playing Minecraft in 3D. The package came from Hong Kong.

Actually, I enjoy Thexder, Into the eagle's nest, Gauntlet, Ms Pac-man, Rogue, ... Those games are great if only you can tolarate text mode, CGA 4 colours / tandy 1000/PCjr modes and PC speaker.

Playstation TV is a device to let you to play Vita on TV. Vita is a handheld system.

I know that.

Only if you consider NX as a handheld console.

Nintendo doesn't want everybody to steal its intellectual properties but ... Nintendo likes to steal use people's ideas. I wonder if we could licence an idea like "let's make a cartridge console system" and protect it.

Thanks for the advice, Kiwi. Now, I can use all the screen modes. I noted in mode 3 (multicolor mode), the text is scrambled but the sprites still work.

With the help of Kiwi, I can now go all colecovision screen modes. This new rom will go all screen modes. modes.rom Just wait for a moment, the program will switch to another screen mode.

I spent all the day if I can use all screen modes on Colecovision Modes 1 and 2 are easy. But I can't get screen o and 3. Mode 0: Reg/Bit 7 6 5 4 3 2 1 0 0 - - - - - - M2 EXTVID 1 4/16K BL IE M1 M3 - SI MAG 0 0 0 0 0 0 0 0 1 0 1 0 0 0 0 0 vdp_out(0,0); vdp_out(0,0xA0); I disabled BL because screen 0 has no sprites anyway. This code doesn't work Mode 3 Reg/Bit 7 6 5 4 3 2 1 0 0 - - - - - - M2 EXTVID 1 4/16K BL IE M1 M3 - SI MAG 0 0 0 0 0 0 0 0 1 1 1 0 1 0 0 0 vdp_out(0,0); vdp_out(0,0xE8); This code doesn't work either I expect the letters in mode 0 would be smaller And mode 3, sprites would be look with big pixels. I will stick with mode 2 since, the characters are big enough and the sprites are just fine.

Thanks for the tip.

Thanks.
