|bell.zip||28k||12-05-05||Bell link library|
The Bell link library is a tool for assembly programmers that eases the development of multiplayer games through the link port. It was created several years ago but I have only recently recovered it. The manual can also be found online at http://bell.timendus.com/
|binarysearch.zip||3k||20-04-08||Binary Search (general-purpose)|
Binary Search as an efficient algorithm for searching sorted data. The core of the algorithm is straight-forward, and the same regardless of the kind of data. This routine provides the core of the binary search routine, you just need to provide a routine (pointed to by IX) that compares two pieces of data. This means that you can use this binary search to search even your weirdest data formats! Great for parsers (comparing a text string to a sorted list of function/var names) or even just searching data like a Pokemon database by name :)
|bintobcd.zip||2k||02-07-26||Binary to String|
Two routines that format integer numbers to ascii strings that are printable using _puts or _vputs.
|bitfunctions.zip||3k||06-12-24||Doublewide masked/unmasked sprite routine|
Includes bitshift.inc, my include file for 16-bit bitshifting for all three 16-bit registers, boolean.inc, which contains routines for running a bitwise boolean on hl with de or bc, and doublesprite.inc, which contains my routine for displaying a 16-bit sprite (the usual size is 8-bit) on the screen. The routine is in XOR logic, but can be changed to AND, or OR logic. Refer to readme.txt for info on input registers for the sprite routine. Now also includes doublemaskedsprite.inc, which is my sprite routine for a 16-bit masked sprite. I've also updated to old sprite routine to be much faster, and doesn't use IY, and i made some of the bitshifting routines faster.
|boldfont.zip||3k||03-11-03||Bolder Font Puts Routines|
These only 99 bytes routines are able to use bolder font version of _vputmap and _vputs. Also includes multi-line version. Please read "boldf.inc" and "sample.z80".
|cpstrupdate.zip||1k||04-10-09||Updated CpStr( )|
Not long after I had uploaded the cpstr routine to the archives, did I get an email from Joe Pemberton that included a much better coded version of the function. This updated version is both faster and smaller. Also it is not limited to strings<256 chars in size (not that you'd really need a string that big, except in the rarest of cases). Returns results to z80 flags Z is ste if they are equal, NZ if they are not equal. Also when NZ is set C means str1[pointed to by hl] comes alphabetically after str2[pointed to by bc], NC means str1 comes before str2. If anyone wants to make a command-line based program/operating system, this is probably a good function to have.
Dline is line drawing routine thats faster than Patai Gergely's Drawline, One version allows interrupts to be on, doesn't use write back and is 6% to 20% faster. The other is 40% faster and needs two bytes to save the SP. Note both sacrifice memmory for speed.
|fancydonkeygfx.zip||7k||19-11-12||Fancy Donkey GFX: Line, Circle, Filled Circle|
These are line and circle drawing routines. What makes them Super Snazzy (tm) is that you get to provide a pointer to the plotting routine via IX. Hmm, let me clarify-- If you want your circle to be drawn with pixels, you pass a pixel-plotting routine. If you want to draw your circle with a bunch of mini circles, you pass a mini-circle drawing routine. If you want to draw a line whose every tenth pixel is actually a filled circle, you pass IX pointing to a routine that counts and plots pixels, opting for a filled circle every tenth call. These routines are versatile as h*ck. Check out test.z80 for examples.
|fastcirc_8x.zip||2k||04-01-20||FastCircle TI-83 Plus|
Bresenham's circle algorithm. MUCH faster that the TI-OS routines.

|keyin.zip||3k||02-06-19||Keyin - Key input routine that uses IY|
Keyin allows you to save all keys in statvars and check it with " Bit ? , ( IY + ? ) ". No longer needing reload key data into A. And since Iy never changes you can read key data at any point in your program. This routine is under 25 bytes and fast.
A fast line-drawing routine and a line-clipping routine. You can draw a line between any two points on the screen. The clipping routine lets you draw lines that are partially off-screen.
|movingball.zip||11k||03-11-19||(Medium) Greyscale Sprite Routine (8 Directions)|
This file includes the two routines I made, it moves a sprite (One in Black & White the other in 4 level greyscale) with the directional pad (8 Directions). The routines are include, the compiled files too. For the Greyscale, you need Diederik Kingma's greyscale package. (www.maxcoderz.com). Read the Readme.txt for further instructions.

This is a run counter that demonstrates Self Modifying Code (SMC) and Binary Coded Decimal (BCD.) This run counter also returns a number, in Ans, that can be used in a BASIC program. This is an update to my 8-bit Run Counter. If you only need to count to count to 99, use the 8-bit one, it is smaller and faster. This one will count to 9999.
This is a run counter that demonstrates Self Modifying Code (SMC) and Binary Coded Decimal (BCD.) This run counter also returns a number that can be used in a BASIC program.
|scalespr.zip||12k||01-06-27||Scaled Sprite Routines|
Two sprite routines which allow you to draw sprites at a fraction of their stored size. The sprites may be drawn with a scale factor anywhere from 0.4 to 100% -- so sprites can only be scaled down, not enlarged.

A graphical routine that allows to apply a 16*16 texture on a ground and to "bend" it. Demo program included for Ti83 (Venus 2.3) and Ti-83+(SE) (ION). This update is a slight optimization and the demo program has the right header for Venus 2.3 now.
Rotates image on screen or in buffer. Good for moving backgrounds.
|somesimpleandusefulroutin.zip||1k||04-09-16||A Few Simple And Useful Routines|
Just some routines, that may be useful. Kinda aimed toward begining asm programmers. Some of these routines are born out of the fact that the Z80 does not have 8 and 16 bit versions of ALL instructions.

This project was inspired by Sean McLaughlin's heapsort implementation and is all original code. **Now with a smaller, general-purpose version and listsort example.
|z80stringcompare.zip||1k||04-07-11||Z80 String Compare|
Ever wanted to compare two strings with none of the hassle of programming it yourself? Very useful for people who are planning on making comand line based programs in z80. NOTE:Do not use this in a time-critical section of code, even though it is NOT painstakingly slow, it's not lightning fast either. PLEASE CONSIDER THIS!!
