Created by Steve Kwok in just one year (!), This emulator from Sega Saturn
called Nova is able to run several commercial games, but it is still in its
infancy. Nova is written in C ++ 11, and aims to reach the same level as
other home console emulators.
Nova was therefore written from scratch and in ONE YEAR ONLY, but his writing
is inseparable from the research and contribution of many authors of
emulators.
Nova does not currently support games from the CD-ROM drive, but instead
reads the following CD image formats: .cue, .mds, .ccd, .bin.
- SH2: Added read byte access of TIER register of FRT(3D Lemmings (E))
- SCU: Refactored INTC
- SCU: Made DSP and DMAC as separated excutable devices
- SCU: Supported irregular(Transfer address is not aligned or transfer count
is an odd number) DMA transfers
- SCU: Implemented better timing for DMA transfers
- SCU: Implemented better synchronization mechanism for DMAC
- SCU: Implemented caching of DMA triggers
- SCU: Implemented priority for the three DMA levels
- SCU: Implemented all status(Access, Interruption, Standby, Operation) of
DMA transfers
- SCU: Implemented Force-Stop of DMA transfers
- SCU: Implemented handling for illegal DMA
- SCU: Implemented handling for the Status of Stopped DMA registers
- SCU: Added handling for DSTA register
- SCU: Added "Cool-down" time for interrupted/Force-Stopped DMA transfers
- SCU: Added restrictions for register access
- VDP1: Added restrictions for register access
- VDP2: Fixed the VBLANK bit of TVSTAT register
- CDB: Refactored handling of DATATRNS register
- CDB: Added byte access of DATATRNS register(Steam Hearts via SCU DMA)
- SYSTEM: Added checking for accessing device registers from slave SH2
- MISC: Refined regular expressions of the CUE parser
- MISC: Fixed regular expression bugs of the INI parser
