Call of Pacman

I wanted to share this...

 

Ever since I saw that post on the programming forum that is no longer there, I wanted to try doing full motion video stuff for the Colecovision. I decided to leave the color table data out and use fill_vram to fill in the color table, so 1-bit video would play. I created the animation in Cinema 4D, and used cell rendering feature to render the animation in 1 color. Then render a frame at a time and save it to bitmap. I don't know how to extract bitmap as a 1-bit pixel table so I booted up Paint Shop Pro 4 and mass open all the bitmap files I made for the scene. And also booted up CVpaint 2 since it load/process picture from the clipboard. I used copy to get the frame into the clipboard, and in CVpaint, I clicked on paste and loaded the picture as a black and white picture. And produce a .c file as a rle'd data.

 

I used Cinema 4D to help me draw Pacman and ghost in CVsprite 2. I wanted Pacman to be 2 sprites a line, but it'll take more sprite data to store the punched out version of the sprites. The ghosts are 2 sprites a line. I flickered between 2 sprites to add an additional color to pacman and the power pellet. I had to do the same for Flappe Byrd Medal scene.

 

And the game itself is kinda making fun of modern game for being too easy and handholdy. This game have 4 FMV animation sequence, the title, board zoom in scene, Pac death scene, and the winning scene. I made MSPAC being the support person like Roll in Megaman Legend or Navi in Zelda:OoT. Score wasn't important in modern game so I left out the scoring feature. Just get to the Power Pallet and you have beaten the game. Also, the enemy doesn't even attempt to chase after you in this game.

 

I may expand using this FMV idea. I haven't yet make a 256KB or 512KB ROM. Just 128KB that is successfully made. The very least, I do want to make a FMV stuff for my 128KB version of Rockcutter, so these 4 pages of data have something in them.

That's pretty awesome. ;)

 

I did some work on raw video conversion on the TI side, I have a script that will output raw video data interleaved with audio - though I haven't written a Coleco player due to memory usage. I use only half the bitmap screen to improve frame rate, but it still chows down memory fast... even a 1MB megacart doesn't go very far.

 

But, if you're curious check the thread here - it links to some YouTube samples (some of which are down) - http://atariage.com/forums/topic/234632-animation-playback-on-the-ti-994a/

ROM: BTshort.rom

 

I was curious how well it handles doing both pattern and colors table. Not really well. 3-4 frames per 16KB bank. At least the majority of the Burgertime short I did 8 years ago made it in. After all, Burgertime was the game that made me get a Colecovision.

Here's the short:



Tursi, I did come across that animation thread. I thought it was really cool!! I did send my sister the link of Frozen, Let it Go few years ago. When you say memory, you're referring to ROM size? I think the Ultimate SD cartridge might use up to 1024KB, it has the 512KB ROM that test bankswitching.

I would suggest only 128 chars per section and use a hidden switcheable pattern screen in order to avoid update glitches.

Yeah... my smallest sample is the SpaceBalls clip, that requires 2MB of ROM. Most of the cart samples I made at 16MB, and a few hit 32MB (which is the TI's theorhetical maximum with the bank switching scheme we are using - no hardware larger than 2MB exists yet though).

 

Loving your clips though :)

Kiwi, if you send me the loose frames of your burger time animation I would try to adapt some msx tools I developed few years ago.

Hi there, Kiwi. I was able to port this to MSX, I can show it to you if you're interested. 🙂

Cool!  Sure.  Pretty neat you were able to convert C converted to asm code to the MSX.  I still have the source code, however the 3D objects were not saved. 

Speaking of smooth scrolling, I've been experimenting with smooth scrolling lately. 
SmoothScroll.gif.134651363a7cb1459afb1c7068155eeb.gif

The game's very early.  I load the char in 0x0400,0x0c02,0x1404, 0x2c06.  So it's shifted by 2. What I'm doing is doing like what NES does when changing CHR-ROM bank, I'm loading new value to the register that holds the address for the CHR.  I'm doing this in screen mode 1(1 char/color table), since the mirroring bug doesn't occur in that mode I believe.  It copies from the main screen, and paste to the other screen 3lines a frame.  Then draw new strip on top before flipping to the other screen.  It has enough time to do 6 rows I experimented, but it leave little leftover for CPU time and I'm running the game at 30 fps.  4th speed probably going to be used for escape sequence. I'm using 32 bytes of RAM to do this.

Don't forget you can use the Magellan tool to create large maps and have it automatically generate the characters needed for smooth scrolling.

 

I haven't done much with it myself, but it can save you some time -

Okay, I will be just there on the MSX site soon. BTW, I would love to also convert this to MSX too. 🙂

I have this too, IDK if I can convert this to MSX though.
