Acknowledgement

Of course, many thanks to viletim for his initial CPLD-based DAC project, for providing a valuable commercial modding board as well as for publishing the schematics and source codes for that project. I also want to send many thanks to Ikari_01. He has written the code to detect 480i and PAL/NTSC output with the CPLD. He provides a source code for the XC9572XL, which can be accessed here: URL to Ikari_01's GitHub repository Last but not least, thank you to Bob for his website RetroRGB and especially in this context here for collecting and sharing all the RGB information regarding the N64.
