We have seen how PumpkinOS runs a classic 68K application. First, code.0 and data.0 resources from the PRC are loaded and decoded. Then code.1 is loaded and the 68K emulator starts running it. Native applications, that is, applications compiled from source to the target architecture of PumpkinOS (x86 or ARM), are still stored in PRC files, having access to all PalmOS resources like forms, bitmaps, alerts, etc. In fact, the same resource compiler (pilrc) used to generate the binary resources for PalmOS is used in PumpkinOS. The difference lies in how code and data are stored and processed.
PumpkinOS'; developer also sent out a tweet with a video of a new shell - which looks quite cool.
