Notes

Building mame for the CD-i

make SOURCES=src/mame/philips/cdi.cpp REGENIE=1 -j8

Using mame

./mame cdimono1 -log -oslog ./mame cdimono1 -verbose -log -oslog -window &> log

Swap 16 bit endianness

objcopy -I binary -O binary --reverse-bytes=2 picture.bin picture2.bin

Transmit binary

scp 68ktest.rom root@mister:/media/fat/games/CD-i

Ripping from CD to single CUE/BIN

In this case, a single bin

cdrdao read-cd --read-raw --datafile cdimage.bin cdimage.toc

then byte swap and generate cue

toc2cue -s -C cdimage2.bin cdimage.toc cdimage.cue

Convert CUE/BIN to CHD

chdman createcd -i cdimage.cue -o cdimage.chd

Convert CHD to single CUE/BIN

chdman extractcd -i cdimage.chd -o cdimage.cue 

Convert CHD to multi bin CUE/BIN

chdman extractcd -i cdimage.chd -sb -o cdimage.cue

Simulation speed

Vcd: --trace Written video_00.png after 44.36s -rw-rw-r-- 1 andre andre 2,5G 9. Sep 13:04 /tmp/waveform.vcd

Fst: --trace-fst Written video_00.png after 51.33 -rw-rw-r-- 1 andre andre 49M 9. Sep 13:02 /tmp/waveform.vcd

This means Fst is better as it is much smaller

Auto save of NvRAM?

Seems to be not desired:

• SD Card wear out?
• Point of time to write is random?
• Unresponsive as it steals cycles from HPS IO?
