CHANGELOG

@@ -15,6 +15,7 @@ v0.1.1a (bugfix release)
 v0.1.2
 ======
 
+ * New menu entry: "System Information"
  * Auto region override (eliminate "This game pak is not designed..." messages)
  * Improved mapper detection (fixes Batman vs. Joker and many PD ROMs)
  * Improved data streaming performance
@@ -22,3 +23,74 @@ v0.1.2
  * A and B buttons swapped in menu to match common key mappings
  * Fixes:
    - MSU1: Stop audio playback on end of audio file
+
+
+v0.1.3
+======
+
+ * Updated logo gfx with new version from klaptra
+ * Updated font to distinguish between 1 and I
+ * Menu layout adjusted to move status line up by 4 scanlines
+ * Run previously loaded game by pressing Start in the menu
+ * Auto-scroll file names that do not fit the screen
+ * SD access time measurement on System Information screen (takes a while!)
+ * Cx4 memory map: mirror ROM to 40-7e/c0-ff (fixes MMX3 Zero patch)
+ * Some FPGA configuration error detection (mainly useful for hardware diag)
+ * Fixes:
+   - FPGA-side SD clock pullup (increases reliability with some cards)
+
+
+v0.1.4
+======
+
+ * SPC Player (contributed by necronomfive/blargg)
+ * System Information screen now shows CPU/PPU revision (contributed by necronomfive)
+ * Satellaview: basic data transmission packet support (makes some more games boot, thanks to LuigiBlood for assistance and sample data packets)
+ * Number of supported files increased to 50000 per card / 16380 per directory
+ * Slight speedup of menu text rendering
+ * Reduce load time of menu
+ * Adjust Cx4 timing to be more faithful
+   (Mega Man now defeats the boss in attract mode in Mega Man X2)
+ * adapt ROM mirroring size to file size if header information is invalid
+   (fixes Super Noah's Ark 3D, possibly others)
+ * MSU1 interface changes suggested by byuu:
+   - Data offset 0 and audio track 0 are automatically requested on reset.
+     This causes the busy flags to become 0 shortly after reset/startup.
+   - $2000 bit 3 is now "audio error", becomes valid after "audio busy" -> 0
+     set when an error occurred while preparing playback of the requested audio track
+ * write LED stays on when SRAM content changes constantly
+ * Fixes:
+   - fix empty save files on FAT16 / incorrect free cluster count on FAT32
+   - correct directory sorting (force parent directory at top of list)
+   - fix text corruption when entering a directory with a scrollable name
+   - fix files/dirs count in system information
+   - make 'sd2snes' directory hiding case-insensitive
+   - improve DAC I²S timing
+   - fix occasional palette corruption in menu
+   - fix SD clock glitch on ROM loading (occasional glitches/crashes)
+   - fix memory write timing on ROM loading (occasional glitches/crashes)
+   - fix SPI timing (ROMs not loading; System Information not working)
+   - properly synchronize SNES control signals (occasional glitches/crashes)
+   - fix floating IRQ output (occasional glitches/slowdowns)
+
+
+v0.1.4a (bugfix release)
+========================
+
+ * Fix DMA initialization in the menu (could cause sprite corruption in some games)
+
+
+v0.1.5
+======
+
+ * Sort directories by entire file name instead of first 20 characters only
+ * Correctly map SRAM larger than 8192 bytes (HiROM) / 32768 bytes (LoROM)
+   (fixes Dezaemon, Ongaku Tsukuuru - Kanadeeru)
+ * SPC player: fix soft fade-in (first note cut off) on S-APU consoles
+   (1CHIP / some Jr.)
+ * More accurate BS-X memory map
+ * Ignore input from non-standard controllers (Super Scope, Mouse etc.)
+ * Fixes:
+   - minor memory access timing tweaks
+     (should help with occasional glitches on some systems)
