Basically, whatever triggers the NES channel to output sound (length counter settings, etc - I don't remember all the APU register that trigger a re-enable off hand). Then when an update comes along to reset the length counter (or such) then turn on the PCE channel. But for enabling a channel - don't! Rather, set a status that the channel is operable - but don't turn it back on. You can use that to turn off the channel if the corresponding bit is set to disable. It's been a minute, but last I worked with NES APU, the control reg ($4015) sets the length counter to 0 to disable a channel. Suggestions - ideas for the port would be very welcome! adding atmospheric effects like foreground clouds, or a background color gradient for the sky.
using 16 colors palettes for the tiles and sprites rather than 4
sound emulation ( I have 0 knowledge of low level sound wish me luck ) Vertical scrolling is done through a RAM buffer of the nametable (best way I found to deal with wrapping the 60 CHR rows of the NES with the 64 rows on PCE), rows being copied to VRAM with a moving offset. sprites are translated from the NES OAM to PCE SATB at run time (lots of lost space due to 8*8px NES sprites being stored centered in 16*16px PCE sprites) set up the ca65 project (found a recent branch that supports the ZP at $2000) since the NES games was assembled with ca65. I will try to post regular updates about the progression. I contacted Morphcat games 2 months ago and pretty quick got their source code to start porting the neat 2019 homebrew Micro Mages from NES to PCE. It does not store any personal data.Being a game and apps C/C# developer since 1999, I wanted to experiment assembler and homebrew dev on my favorite system (coregrafx bought in France Nov 1990).
