Out of WN... Oehlinger is not a company, just a guy inside Fun World that climbed to CEO of PhotoPlay.
He left some strings with his last name in some programs and claims to be the CEO and owner of Funworld Ag...
- Add custom keyboard port and emulate most of the Expanded Typewriter Keyboard
- Add unidirectional printer port
- Use addressable latch devices to control various things, including disabling display during RAM test
- Hack to pass non-volatile memory test on uts10
* Adjusted UART receive behavior to flag an available byte only at the specified baud rate.
* Added separate UART baud rate calculation for SPG24x vs. SPG28x.
* Adjusted ADC behavior to flag an IRQ when the relevant data bit is set, not when register bit is newly set.
* Added separate logging for FIQ registers.
* Added logging for SIO registers.
-clickstart: Added preliminary mouse hookup. Only accepts a mouse update once, ignores further updates. Needs further investigation. (nw)
new NOT WORKING
Mattel Classic Sports [Sean Riddle]
Dora the Explorer (JAKKS Pacific TV Game) [Sean Riddle]
kludge handling of invalid size writes to DMA so that Dora the Explorer doesn't trash all of RAM + registers
new SOFTWARE LIST
JAKKS Pacific 'NK' Game Keys
(Dora has corrupt gfx, probably the bad DMAs should do something, Mattel Classic Sports gives a black screen)
xavix.cpp:
new NOT WORKING
e-kara Pro Headset (US, includes 3 songs) [Sean Riddle]
Super Dash Ball (Japan) [Sean Riddle, Peter Wilhelmsen]
Gururin World (Japan) [Sean Riddle, Peter Wilhelmsen]
disable active raster interrupts if raster interrupt enable is turned off, and add preliminary shifter register emulation, needed for 3D stages in Gururin World [David Haywood]
(Pro Headset works as well as other e-Kara stuff, marked as NOT WORKING due to lack of microphone and sound emulation issues, Super Dash Ball needs trackballs hooking up, Gururin World needs analog cycle looking up)
rad_eu3a14.cpp:
tied tilemap dimensions to tile sizes to improve Huntin'3 map screen [David Haywood]
The 7497 device should now work as described in the TI datasheet. This
datasheet contains an internal schematic with details on gates and D
flip flops used.
If you can parse this comment from the Linux driver, please help :)
* The IOASIC LANCE devices use a shared memory region. This region
* as seen from the CPU is (max) 128 kB long and has to be on an 128 kB
* boundary. The LANCE sees this as a 64 kB long continuous memory
* region.
*
* The LANCE's DMA address is used as an index in this buffer and DMA
* takes place in bursts of eight 16-bit words which are packed into
* four 32-bit words by the IOASIC. This leads to a strange padding:
* 16 bytes of valid data followed by a 16 byte gap :-(.
I get the first part, which is that since the DMA engine works in words and
LANCE works in half-words that each half-word for LANCE is packed into one
word from the CPU's point of view. The second part not so much.
