I started playing with the SPC700 and I want to reproduce one sample.
Im using the "cymbal.brr" sample that 93143 posted here:(basamples_v2.7z)
viewtopic.php?f=12&t=10696&start=120#p142336
The situation is the following:
-I have written one 65816 routine that can upload data to the APU RAM and set the execution address
-I can transfer the sample and the program.(The SPC700 executes my program without problem)
-The sample and the program are stored in the ROM like a single binary file , organized in this way:
Code: Select all
$0000->|--------------| \
| SAMPLE | | "cymbal.brr" 17010 bytes
$4272->|--------------| /
| Program |
$43B6->|--------------|
This is my SPC700 code:
(I'm unexperienced with the spc700 , I dont know the instructions & addressing modes , so be kind and dont laught too much
)
Code: Select all

bra -Any example of how to do this?
Any brr test sample?
