Known bugs in Nestra v0.66:
The following is a list of known problems in the current version of NEStra.
Let me know if you have a fix for any of these problems, or if you find any
other bugs not listed here:
- A few cycle times aren't counted accurately.
- Self-modifying code doesn't always work right.
- Some instruction forms do not handle I/O and will produce a breakpoint
trap if used that way. Use -i to ignore them, and send me a bug report
if you encounter this problem.
- The following instuctions do not check for mapper writes: ASL LSR ROL ROR
- I suspect that the sprite code isn't completely correct; please tell me
if you know what the problem is.
- Mirroring of the internal 2K RAM is not emulated.
- Doesn't implement the 6502 wrap-around bug (I really doubt that this
would make a difference)
- Video code needs to be optimized for speed.
- No sound.
- No PAL mode (I don't have any games that need it)
- MMC2 support is incomplete
- Needs more mappers - submissions are welcome!
