Doctor
V64 BIOS Description
Bios V1.83 for Doctor V64 :
just fix the bug in V1.82 to re-enable track no. up or down
selected by '|<<' and '>>|' in VCD playing.
Features of Doctor V64 Bios V1.82 :
1. Plays all MPEG I files ('.mpg' and '.dat') in CD even
its size over 128M bytes.
2. Full functions in MPEG I files ('.mpg' and '.dat') playing
works like playing a VCD (fast forward, fast backward, pause, adjust the audio channels
and volumn, slow motion and video capture).
Features of Doctor Bios V1.81 :
Plays all MPEG I files ('.mpg' and '.dat') in CD once
the 'Play' button is pressed. Playback of all files will be in looping mode until the
'Stop' button is depressed (max. of 85 MPEG files inside CD).
Play '.mpg' or '.dat' MPEG I files downloaded from PC
and show it continuously until the 'Stop' button is pressed.
Select a '.mpg' or '.dat' file from the CD file
selection screen and it will play continuously until the 'Stop' button is pressed.
To access the CD files selection screen while the V64 is
in *input mode, hold down the 'Stop' button and pressed the 'Play' button. Otherwise it'll
play the MPEG I files in CD. Following access to CD files selection screen will be
just be by pressing the "Play' button until the CD tray is opened or a new CD is
loaded.
All the useful functions allow the V64 to
become a portable presentation device! Demonstration of
games, product information, advertisement, etc
can be stored in MPEG files and be playback on the V64 in retail stores. Basically, it can
also be used for meetings or any other presentation occasions.
*Input mode refers to the screen when the V64
is first turn on or when the 'Stop' button is pressed
after the playing a VCD movie or a series of '.mpg' or '.dat' files.
Features of Doctor Bios V1.80 :
1.Real video and audio MPEG demo files can be used for
game selection : It can search and playing '.mpg' MPEG files of demos in a CD
automatically and upon 'Play' or '>>' or '<<' button pressed to load the
corresponding game file or to play next mpeg demo file or previous mpeg demo file.
After the game file loaded, the Bios will wait
for you to switch on N64 to run game and when you switch off N64 later it will return to
MPEG demo playing loop. So the V64 + N64 can be used for games demonstrating and even used
in acrade game centre with legal license CD game files and MPEG Demo files.
If you press 'Stop' button during the Bios
waiting for you to switch on N64, it will return to 'Stop' waiting for input mode.
If no game file corresponding to a MPEG demo
file, the Bios will not play the demo to you, so you can enjoy the games selected basing
on some wonderful MPEG demoes.
If you want to run other operation (e.g. load
'sav' or '.ips' files) with a CD consisted with some '.mpg' file, just press 'Stop' button
before press 'Play' button to run CD file selection at normal situation. If you press
'Menu' button during reading headers of files to skip the procedure, then when you only
press 'Play' button to run CD next time, it will go to the MPEG demonstration again; if
you wait until whole procedure of header reading completed, then the Bios will stay in the
non-demo mode and anytime you only press 'Play' button to run CD file selection at normal
situation until the CD changed or the V64 switch off and on again.
2.If your Bios combined with a upload sram utility (for
example, the 'Up SRAM V1.2') then you'll get the great convenience on uploading a SAVE
data file into DX256 or the game cartridge because the Bios V1.80 will load the utility
automatically after a '.sav' file loaded from CD or downloaded from PC and then waits for
N64 to be switched on to run the utility. After N64 on, the Bios will waits N64 off again
and then return to file selection operation screen so you can load game file after the
save data uploaded easily.
If your Bios don't combined with a upload sram
utility, Bios V1.80 is no diffence in '.sav' file loading procedure compared with earlier
version.
The Doctor V64 Bios V1.80 will be released on May 5,
1998 officially.
Features of Doctor Bios V1.75 :
Please replace the Bios V1.74 with V1.75 to solve the
bugs in Audio CD playing.
We're sorry to have inconvenienced you.
Features of Doctor Bios V1.74 :
Please replace the Bios V1.73 with V1.74 to solve the
bugs in CD drive operations.
We're sorry to have inconvenienced you.
Features of Doctor Bios V1.73 :
1. Auto detect door opened or closed of CD drive and
take right operations so you can place a CD in the tray of the CD drive and just press
'Play' button to start.
2. Enable error try in data loading so you can read CD-R
of more brands in your V64's CD drive.
3. Easy upgrade: prevents the problem of just showing
'loading...' and dead in Bios upgrading.
Features of Doctor V64 Bios V1.72 :
1. Speed up the time of 'waiting...' when you first
power on V64 and press 'Play' to load game CD.
2. Speed up the time of 'waiting...' so much to let you
reach the file selection screen quickly.
Remark: If you open the CD tray, change a CD in it, then
you need to close the CD tray manually for this new Bios version.
Features of Doctor V64 Bios V1.71 :
1. Add a Menu operation for swaps bytes in DRAM to run
other's non-swapped file format games loaded from CD or downloaded from PC.
2. Speed up the operation of 'upload DRAM data to PC' to
half the time but still reliable compares with early versions.
Features of Bios V1.70 :
Can be worked with new released 'tpc2' & 'v64io2'
lets communication between V64 and PC without problems. V1.70 can match old version 'tpc'
and 'v64io'; 'tpc2' and 'v64io2' also can work with old version Bios before 1.70. (Some
printer ports in PC aren't fully match the print port's standard, some bidirectional
signal pins just can work in one direction so that this kind of print port can't work with
Bios before V1.70. Now the new Bios and 'tpc2' and 'v64io2' not only can use the old
bidirectional pins but also can use another direction confirmed pins for communication
without problems.)
All sub-directorys in CD will be displayed with a
spe>
A little improve in CD Drive controlling let more brands
of CD-ROM Drive can be used in V64.
(If you want to modify the background color or H/V
offset of the screen of V64, don't just modify the bytes in first 128k byte but the second
128k byte too. For example, if you want to change the data in 00002H then you also need to
change the data in 20002H to the same value.)
Features of Doctor V64 Bios 1.61 :
You can press 'Menu' button during headers reading of
game file in CD to stop the headers reading and go into file selection immediately.
The headers reading procedure just run once until CD
changed. That means don't need to read headers each time you want to load file from CD
after headers reading completed in once.
You can choose your favourite background color of V64's
screen by changing the 3rd & 4th byte of the Bios to new values :6b, 80 for green; 80,
80 for black; 6b, ff for blue;
You can choose the start point of V64' screen in H/V
offset by changing the 5th(V) & 6th(H) byte of the Bios to new values.
Well improved in ATAPI command control let more CD
drives of different models and different brands can be used in Doctor V64 (Panasonic,
Sony, Toshiba, Mitsumi, Hitachi, Liteon, ...).
Features of Bios V1.60:
- Add two new Menu functions which Can read the 128k byte
data from DX256 and upload to PC or download 128k byte data from PC to DX256.
- Enhance the power of file/dir processing:
The game name & version & file
size now can be showed in bottom of screen upon the cursor pointed a game program image in
file selection operation.
Even empty dir can exist in CD (it'll
cause error in Bios V1.53).
