NO$GBA v1.1
axw - ore 11:06  :: commenti (0) ::

Ennesima release di questo emulatore/debugger, pensato principalmente per le compagnie di sviluppo. Ricordo che le versioni per uso privato infatti non consentono di far partire roms commerciali. Di seguito le novità:

• video: fixed bg mode 0 double map-ysiz (shr eax,6 (instead 5) for 4000h->100h)
  
• cutdown: split into separate sound and color versions as additional protection
  
• io/dma: emulates address reload upon dma re-start (bios dma-fifo intro sound)
  
• sound: emulates digital FIFO/DMA sound channels (not sure if volume+stereo ok)
  
• i/o map: bldcnt deciphered (not sure if there may be only ONE target each ?)
  
• i/o map: deciphers mosaic bits, and bldalpha and bldy (eva,evb,evy)
  
• help: re-sorted bit numbers in sound chapters (incrementing 0..15 ordering)
  
• help: added note about buffer synchronization in DMA/FIFO sound chapter
  
• i/o map: displayed channel 3 waveram banks, deciphered sound control bits
  
• i/o map: deciphers keycnt irq enable/condition bits
  
• i/o map: deciphers waitcnt bits, displays bios irq vector [3007FFFh]
  
• io/timers: added auto-reload for count-up timers
  
• io/timers: changed timer IRQ address to 202hex (instead 202 decimal)
  
• io/timers: repaired badly inverted count-up bit
  
• internal: changed dma/timer macro param ch to chn (ch could be a 8086 reg)
  
• sound: implemented "FM" channels 1-4 (from no$gmb, with GBA modifications)
  
• internal: replaced cs32:[gba_intcount] by vals [gba_eintcount] (multi gbas)
