Programming Libraries and Engines
Below are links to various library functions, as well as programming frameworks (aka "engines") that you can use when building a game. After all, while inventing wheels is sometimes fun, more often than not it's more fun to focus on writing a game.
If there are specific functions or library elements that you'd like to see, put a request on the "discussion" page.
Basic Math
- Multiplication
- (to do)
- See also: Tutorial on using shifts for multiplication
- Division
- Signed and unsigned divide: dividivu.asm
- Optimized unsigned divide: fastdivu.asm
- See also: Tutorial on using shifts for division by powers of 2
- Square root
- Integer and fixed point square root: sqrt.asm
Game Math
- Distance computation: dist_fast.asm
- Random number generation: rand.asm
Memory Management
- Bank switching
- Intellicart bank switch utility routines ic_banksw.asm
- To do: ECS-style bank switching routines
- Game variables
- Macros for declaring variables: dseg.mac
Basic I/O
- Status display
- Printing strings: print.asm
- Printing number
- 16-bit decimal numbers: prnum16.asm
- 32-bit decimal numbers: prnum32.asm
- Hexadecimal numbers: hex_disp.asm hex16.asm
- Hand controller scanning
- Wait for tap / wait for release: wnk.asm
- Comprehensive: (todo -- tends to be integrated with game's event handling scheme)
- Intellivoice
- Core Intellivoice driver: ivoice.asm
- Speaking numbers using RESROM samples: saynum16.asm
- Speaking numbers using AL2: (to do)
- SP0256-AL2 Allophone library: (external link coming; cannot be uploaded here due to license reasons.)
Sprite Engine
The intention is to put a sprite engine here. None present currently.
