A repo dedicated to create an FPGA implementation of the Philips CD-i to be usable for the MiSTer project
This repository is very experimental! Use at your own risk!
The first games are booting. Graphics are glitched and the audio is still missing.
Place cdi200.rom as boot0.rom in /media/fat/games/CD-i.
Place zx405042p__cdi_slave_2.0__b43t__zzmk9213.mc68hc705c8a_withtestrom.7206 as boot1.rom next to it.
- CD-I MONO BOARD low level test is functional
- ROM parity check passed
- Dram test passed
- Nvram test passed
- Cdic test passed (tests only memory...)
- Slave processor test passed
- MCD212
- SDRAM interface according to specification
- ICA/DCA parser partially implemented
- CLUT7 RLE partially implemented
- Display File partially implemented
- SCC68070
- UART interface accessible from MiSTer linux
- Timer IRQ implemented
- Custom bus error frames implemented
- DMA Channel 1 supported
- SLAVE
- Interface to main CPU implemented
- Answers to basic requests from main CPU
- Maneuvering device simulated with MiSTer controller input
- SERVO
- High level behaviour simulation
- CDIC
- Basic data sector reading
- MiSTer
- ISO Mounting via Menu functional
- Automatic boot rom loading for main cpu and slave
Core Utilization:
Logic utilization (in ALMs) 12,066 / 41,910 ( 29 % )
Total block memory bits 632,004 / 5,662,720 ( 11 % )
Total DSP Blocks 47 / 112 ( 42 % )
- Fix graphical glitches on bootup
- Implement the CDIC audio parts
- Fix DYUV (e.g. Tetris intro)
- Simulate seeking time
- Fix servo behaviour of always detecting a disc
- Use the MiSTer framework to save the NVRAM to sdcard
- Only when changes are detected and when the OSD is opened
- The N64 core does it like that too
- Add alternative input devices (a mouse)
- OSD setting for input device conformance (1200 baud)
- Refurbish I2C for the front display and show the content as picture in picture during changes?
- It might not even be required at all.
- Fix timekeeper initial time
This core is tested with these ROMs:
