| Summary |
 05623: MSX2 and MSX2+: Top and bottom screenborders are wrong for both PAL and NTSC |
||||
| Description |
Top and bottom screenborders don't set proper sizes differentiating for PAL, NTSC and its combination with 192 and 212 line modes. The wrong borders also affect games that use the borders for effects. For example the border strobe light in KingsValley II upon completing a tomb is less pronounced than a real machine because of too small borders. |
||||
| Steps To Reproduce | Look in the code msx.c and v9938.c and compare to parameters in Yamaha v9938 technical data book (see page 146 and 147 of the book). | ||||
| Additional Information |
Correct borders can be found in the table below (values taken from V9938 technical data book page 146, 147. * PAL NTSC * 192(LN=0) 212(LN=1) 192(LN=0) 212(LN=1) * ------------------- -------------------- * 1.
