Nintendo 64: Doctor v64 FAQ
Q: Unable to transfer file between PC and Doctor V64
A: Please make sure that you are using 'tpc2.exe' and not 'tpc.exe'. 'tpc2.exe' can be downloaded from our download page in our web site. We suggest user to upgrade to the latest BIOS version, in order to support all parallel/printer port modes (SPP, ECP and EPP). If the Doctor V64 has BIOS prior to BIOS version 1.70, set the parallel/printer port mode to Standard (SPP) and use a printer extension cable not longer than 6 feet. Doctor V64 only support data switch/printer extension cable and we suggest that the cable length is not longer than 6 feet. Standard parallel/printer port that are built-in in PC's motherboard can usually support up to 6 ft cable, if the PC has a separate independent parallel/printer I/O card, cable up to 15 ft can be used. Doctor V64 does not support Lap-Link cable.
Q: How to upgrade the BIOS from CD
A: To upgrade a Doctor V64 with BIOS 1.52 and before, burn a CD-R with ONLY the BIOS inside. Press the 'CH' button before pressing the 'Play' button, then follow the screen instruction. For BIOS 1.53 and after, just burn a CD-R with the upgraded BIOS, load the BIOS like any other ROM files and follow the screen instruction.
Q: How to upgrade BIOS from PC
A: Use 'tpc2.exe' and send the BIOS to the Doctor V64 like any other ROM files. The Doctor V64 will automatically upgrade the BIOS after the file has been fully transferred to the Doctor V64.
Q: Upgrading Faulty BIOS/ BIOS cannot upgrade
A: If the BIOS cannot be upgraded normally or is faulty due to a previous upgrade, please use the 'biosup.r64' program that can be download from our web site. Load the BIOS, it should load like a normal ROM file, and when it states 'You can play game now' load the 'biosup.r64' and follow the instruction on the screen.
Q: Methods of Storing 'SAVE' data for Nintendo 64 system (How save game data are stored)
A: There are three ways that Nintendo 64 system save game memories. Only Doctor V64 provides you the Total Memory Solution. Please click on this link to see the 'Method of Storing' FAQ.
Q: How to upload .sav files? (Please refer to our 'Methods of Storing' FAQ)
A: EEPROM save game files stored in '.sav' files can be uploaded from the CD/PC to the Cartridge's EEPROM or the DX256 by using the UPSRAM 1.2 program. Please refer to the 'Method of Storing' FAQ.
Q: Software Emulators and MP3 player for Nintendo 64 system
A: Bung Enterprises Limited is not working on any software emulators and MP3 players. The recognition of emulator and MP3 file extension function is created in advanced for coders who are working on emulators and MP3 players for N64. Please note that all software emulators and MP3 players are not endorsed by or affiliated with Bung Enterprises Limited. Do not e-mail us on where you can get the software emulators and MP3 players, please check out the web site on our link page for more information. Emulator programs will never be available on our web site and will never be built into the original BIOS release by Bung Enterprises Limited. For BIOS 1.90 and after, files with the following extension .GB, .NES, .SFC, .GG, .MG, .PCE, .NEO, .MP3 and .EMU are automatically loaded into the Doctor V64's DRAM starting from after the first 2Mbytes, starting address will be 0x200000. This is to enable the emulator program to be loaded into the first 2Mbytes.
Q: Why CD-R disc cannot be played on Doctor V64
A: Please make sure that the CD-R is recorded in MODE I, ISO 9660 format. If CD-R is recorded in MODE II format, press the '|<<' button before pressing the 'play' button.
Q: How to use save (.sav) files
A: Regardless of a 64bit game EEPROM save (.sav) file being downloaded from the internet or CD-ROM, it can be uploaded to cartridge's EEPROM or one of the selected bank on the DX256 with Doctor V64 and 64bit game system, it can be easily uploaded with the program Upsram 1.2. UpSram 1.2 can be downloaded from the Internet. To upload the '.sav' file to the DX256 or cartridge's EEPROM, load the '.sav' into Doctor V64 either from CD-ROM or PC download, then load UPSRAM 1.2 and just turn on the N64to run it and the save data will be uploaded into the cartridge's EEPROM or the selected DX256 bank. After the save data has been uploaded, turn off the 64bits game system, load and run the respective game and user can play it with the save data that has just been uploaded. (Please note: If you have uploaded an .sav file to DX256, you got to do it only once, when playing another new game, switch to a new bank then switch it back when you want to play the game again)
Q: VCD movies playback not clear and smooth
A: We suggest users not to play pirated VCD movies, as most of the VCD qualities are poor. Not all CD-ROM drives works perfect with the Doctor V64 for VCD playback. All original VCD movies work fine with the Doctor V64 CD-ROM drives sold by Bung Enterprises Limited. If the CD-ROM drive in the DoctorV64 is not the standard CD-ROM drives from Bung Enterprises Limited, playing back VCD movies might not be clear and smooth. We suggest user to use branded Japanese brand CD-ROM like 'Panasonic', 'Hitachi', Mitsumi, etc. for perfect VCD movie playback.
Q: How to convert captured VCD movie still image to .bmp, .gif, .tif, .jpg, etc file format
A: The captured still image from VCD playback cannot be saved into other format. The captured still image is for displaying as slide show on the Doctor V64 only.
Q: How to capture game image
A: It is not possible to capture the game image, the capture function is only for VCD movie playback only.
Q: Sound is distorted or irregular during VCD movie playback and while playing game
A: Some VCD movies and games are not compatible with the Spatializer 3D Surround Sound chip built into the Doctor V64. We suggest user to switch to 'Mono' or 'By Pass' mode when playing back VCD movies or game that do not work with the Spatializer 3D chip.
Q: How to transfer EEPROM save data to a computer and how to extract an '.sav' file
A: The following is for advance user who has good computer knowledge only. It is possible to Transfer EEPROM and DX256 save data to PC with Doctor V64. As the Doctor V64 only support transferring save data from DX256 to PC, to transfer cartridge's EEPROM save data to PC, it must be transferred to DX256 first. Do not slot the DX256 into the 64bits game system, use SRAM Manager 2.0 to transfer cartridge's EEPROM save data into the controller pak, then slot in the DX256 and use SRAM Manager 2.0 to transfer the save data into the selected DX256 bank. Plugged the DX256 directly into the slot on top of the Doctor V64 where the 50-pin connector is usually slot into. Go to the Doctor V64 menu screen and select the 'DX256 Upload to PC' function, then use tpc2.exe or Rtools on the PC to accept the save data from DX256. All 256 banks on the DX256 will be saved as a single file on the PC. It is good to save in bank O_15 if it is not used, as it will be easier to extract the save data, it has the memory address of 00000H. Extract a specific bank's save data from a DX256 file on the PC, each bank is 512 bytes and O_15 has the start memory 00000H, O_14=00200H, O_13=00400H, ??., O_1=01C00H, O_16=01E00H, N_15=02000H, ??., A_15=1C000H, ??, P_15=1E000H, ??, P_1=1EC00H, P_16=1EE00H. Please note that P-16 is designed to pass through (By Pass) the DX256 and 64bits game will read the save data on cartridge's EEPROM instead, but when it writes, it writes to both P-16 and cartridge's EEPROM. Give your friends your save data by simply extracting out the 512bytes from the DX256 file and save it as a file by itself with the extension '.sav' and give it to your friends or release it on the Internet.
