15 Color Brickbuster Mini-Kernel Demo (A2600 Techdemo)
Release notes:Here's a proof-of-concept demo for a brick-busting game with an unusually generous number of brick colors per row (FIFTEEN!). The kernel would require self-modifying code to allow a changing brick field and thus for all practical purposes would require something like a SuperCharger or M-Network cart, but would support three bouncing balls in a one-line kernel.The colors aren't really solid colors, but consist of two colors blended on alternate scan lines. On even scan lines, the colors are black, gray, red, and cyan; on odd scan lines they are black, gray, purple, and gold.Presently, the bouncing balls are tracked in a bitmap with one byte for every two scan lines; each byte is Z-zYyXxq where xyz are the enables for the first scan line and XYZare the enables for the second; q is an end-of-data flag. Data are accessed via (zp),y addressing with a constant Y value ($18 for color gold) and must not be too near the start of a page. If the data were kept in zero-page RAM it would be possible to read it via PLA instruction, but it would be necessary to have some blank scan lines between rows of bricks to reload zero-page RAM from somewhere else.Incidentally, I wonder if this kernel--if built into a game--would set the record for the maximum number of TIA register changes per line in a practical kernel (19!)http://www.atariage.com/forums/index.php?showtopic=82609 Read more about 15 Color Brickbuster Mini-Kernel Demo (A2600 Techdemo)

Lumo has updated his 3DB Loader for the PSP. Changes:Preview v3+ changed doublesided to singlesided meshes&backfaceculling (->draws only visible triangles, front side! ->planes might be invisible, cause of orientation) + new conversion tool (as cmsh might be v2, v3 i just call it v2 now...)+ rewrote maya export script to export the faces in correct* order + added Gouraud Shading ->no more flat view! + added a lightnote: max face/vertex count is 65xxx (not limited by my loader) but you can split your mesh into multiple 3db files and load em up...http://lumo.at.tt/?action=3dmodels Read more about 3DB Loader (31-01-2006) (PSP Application)
ZorBlocks v0.1 (PSP Lua Game)
ZorBlocks is a game by ZordaK. The game consist in clear the screen, removing all the block.If you can remove all and is impossible to continue, press select to make a new board or press start to choose another difficult level. The movements of the block are always down and left, check image ayuda-help.png for better understand. Using rotation have a penalty of -500 points. If you clear the screen without using rotation points i will bonify you with 2x points. To clear blocks at least have to be 2, clearing more blocks at same time will multiply the score for clearing block.http://dl.qj.net/... Read more about ZorBlocks v0.1 (PSP Lua Game)
