Support for selected games that require SmartPort functionality
Support for HDD images up to 512 MB
The existing ProDOS Block Device interface remains fully supported, so current programs and disk images can be used without any changes.
ROM BIOS V1.90N adds SmartPort and large-capacity HDD support while maintaining compatibility with existing software.
Updating the ROM BIOS requires replacing or reprogramming the ROM chip installed on the card.
Free ROM BIOS Update Service
When sending any of my products to me for repair or service, you may also include your SD DISK ][ PLUS card. I will update its ROM BIOS free of charge.
Shipping costs are not included.
ROM Chip by Mail
To receive a programmed ROM chip by mail, please contact me by email.
ROM chip: US$2
Worldwide shipping: US$15
Customers who wish to update the ROM themselves using a ROM programmer may also contact me by email to request the ROM image.
This modified version of the Apple II game Rescue Raiders adds real-time MIDI sound effects through a MIDI card installed in Slot 2.
Gunfire, helicopter machine guns, bombs, missiles, collisions, explosions, and base destruction sounds are triggered directly by the game’s internal events.
Different weapons and explosions use different sounds and volume levels, creating a much more dynamic battlefield experience.
File filtering function: only loadable files are displayed depending on FDD / HDD mode.
Greatly increased file listing capacity: 1,500+ files, which is practically enough for normal use.
“/” swap function: swap D1 <> D2 files.
Key input is no longer case-sensitive.
The screen is automatically refreshed after deleting a file.
Fixed the MORE display “[+]” bug.
Image file size is now displayed in KB / MB.
Smart Cache bug fixes and improvements
Fixed an issue in the write-back cache function when using HDD mode, which could potentially cause problems during heavy write operations.
Smart Cache and several related routines have also been optimized in ASM for higher speed.
SmartPort ready
SmartPort support is already prepared. It will work immediately after upgrading the BIOS ROM chip.
Larger HDD capacity support: With OS support, up to 512 MB per HDD drive can be read and written. ProDOS itself is limited to 32 MB.
**Improved FDD R/W function
This version also includes faster FDD R/W.
However, depending on the NIB image, some disk images may read very slowly. If you copy the disk again using a disk copy tool on the Apple II, the image will be automatically optimized.
You can simply overwrite the disk image with itself using a copy tool such as DISK MUNCHER V1.0 or COPY II PLUS.
Many FDD disk copy programs are supported, including:
Copy the ROM file to the root directory of the SD memory card.
When booting the Apple II, press [S] to enter the SD File Manager.
Press “*”, then press “Y” to start the firmware update.
This version has not been fully tested yet, so there may still be some bugs. Please let me know if you find any issues, and I will reflect them in the next update.
I have finally completed IMS PLAYER for the Apple IIe.
This is the only IMS music player that runs on the Apple IIe. I put almost every feature I could possibly implement into it.
Main Features
Unlimited Music File Size Playback
IMS PLAYER uses a HIDDEN READING method, allowing even very large IMS files to be played all the way to the end without file size limitations.
Massive Instrument Support
Each IMS file can use up to 128 instruments.
Instrument search is performed in two stages:
First, IMS PLAYER searches for a BNK file with the same name as the IMS file.
If some instruments are still missing, it searches again in STANDARD.BNK.
If the instrument still cannot be found, it plays using the default selected instrument sound.
The larger the BANK file, the longer the search time.
Example:
160KB BANK file / about 4,000 instruments: about 4 seconds
670KB BANK file / 15,867 instruments: about 11 seconds
For an 8-bit computer, this is very fast. ^^; While making an IMS player, I somehow ended up building a database search engine.
At first, searching instruments in a 160KB BANK file took 33 seconds. In the final version, it was reduced to about 4 seconds.
Original Stereo Mode
IMS PLAYER supports my own STEREO ON/OFF function, designed to preserve the original character of the music as much as possible.
It first assigns instruments to left, center, or right based on the instrument names, then dynamically rearranges them in real time using my own algorithm depending on the music.
It does not ruin the original feel of the song, and it creates a pretty nice harmonic stereo effect.
Powerful Storage Expansion
An HDD is required, and up to 8 HDD volumes are supported.
In the demo screen, two 32MB HDDs are connected through emulation.
Visual UI Elements
Using an optimized ISR interrupt routine, IMS PLAYER supports:
11-channel level meter
Progress bar at the bottom of the screen
Complete Percussion Support
Percussion is fully supported.
Fast and Intuitive UI & Jukebox
Up to 384 IMS files can be displayed in a single directory.
Non-displayed files such as BNK files do not count toward this limit.
IMS PLAYER also supports a JUKEBOX function, allowing continuous playback upward or downward through the file list.
You can put your favorite songs into one folder, start playback, and leave it running while doing something else.
Pause and volume control are also supported. Very useful when you get a phone call.
Required System
Hardware:
Apple IIe
65C02 CPU
64KB RAM or more
Sound card:
SD Music Deluxe OPL3 card is required
Development Note
During development, I also implemented a file sorting function.
However, it was not very useful in real use and only consumed memory, so I boldly removed it from the final version.
IMS PLAYER will soon be uploaded to the link previously provided to SD Music Deluxe card buyers.
Development was not easy and took a lot of effort. If you enjoy this software, even a small donation would be greatly appreciated.
For questions, please contact me by message or email.
Now, please enjoy the real Apple IIe demonstration.
