Common Issues
SPU Task Crashes (PS3)
SPU Task Crashes (PS3)
Ensure SPU tasks are properly built and linked. Check SPU memory alignment and DMA transfers.
PSN Connection Issues
PSN Connection Issues
Verify PSN configuration and network settings. Check that np_conf.h is properly configured for your title.
Memory Fragmentation
Memory Fragmentation
Use custom allocators and monitor heap fragmentation, especially on PS3 with limited RAM.
Cross-Platform Saves
Cross-Platform Saves
Ensure save data format compatibility between PS3/PS4/Vita for cloud save features.
Cross-Platform Features
PlayStation platforms support cross-save and some cross-play features:- Save transfer between PS3, PS4, and Vita
