bell.zip28k12-05-05File is not ratedBell 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/
bintobcd.zip2k02-07-26File is not ratedBinary to String
Two routines that format integer numbers to ascii strings that are printable using _puts or _vputs.
bitfunctions.zip3k06-12-24File is not ratedDoublewide 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.zip3k03-11-03File is not ratedBolder 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.zip1k04-10-09File is not ratedUpdated 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.zip1k04-07-11File is not ratedDline
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.
fastcirc_8x.zip2k04-01-20File is not ratedFastCircle TI-83 Plus

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.

runcounter16.zip40k09-07-08File is not ratedRun Counter 16-bit edition
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.
runcounter.zip33k08-09-23File is not ratedRun Counter
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.

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.

Four routines to scale sprites (up or down)
scrollingmenu.zip8k07-07-01File is not ratedScrolling Menu for use with BASIC or Assembly

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.
shiftscreen.zip1k04-08-03File is not ratedShift_Screen
Rotates image on screen or in buffer. Good for moving backgrounds.
somesimpleandusefulroutin.zip1k04-09-16File is not ratedA 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.
sortcode.zip2k04-05-12File is not ratedSort
Sorts the vat really fast using insertion sort (fixed a bug)
soundinterruptbeta.zip1k05-09-26File is not ratedSound Interrupts beta

Finds the square root of the accumulator (rounded to the nearest interger) using a lookup table, destroys AF and HL, fast!! 284 bytes total. I have tested this program with VTI (I don't have my Computer->Calc link Cable anymore, sorry) and found it to be bug free, but if you find any errors, email me.
subatomicprint.zip1k04-10-09File is not ratedMicroscopic Print Routines
Two (VERY) small and useful text output routines. Even if you include both it will only occupy LESS THAN 20 bytes of code.
tachyonlink.zip2k03-03-20File is not ratedTachyonLink

tbdcsrp.zip1k03-04-10File is not ratedThe Best D*mn Clear Screen Routine Period
If anyone can figure out a routine faster than this one, then I'll throw away my computer and use an Intel 4004 instead.
tbdsrp.zip4k04-09-09File is not ratedThe Best D*mn Sprite Routine Period
This is a set of four very fast clipped sprite display routines. Includes OR, XOR, AND, and Masked.
_vputs_ml.zip1k03-10-13File is not rated_vputs for multiple lines
This routine works exactly like _vputs, except that it will interperet $d6 as a newline char. This can dramatically reduce code size when using the variable-width text on multiple lines. Now includes a version for the '83+.

Links z80 calcs, fast. Should work on any z80, but has only been tested on the 83+.
z80stringcompare.zip1k04-07-11File is not ratedZ80 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!!
zcomv1.00.zip3k04-07-03File is not ratedZCom - Communication Routine
ZCom is a communication routine for Basic programs. It can transfer real/complex variables and lists, matrixes and strings between two TI-83 Plus calculators. The routine has a built in function to enable chat-programs. This routine is 100% compatible with the TI-83 Plus Silver Edition!
