이안은 뭐하니?

Dear Friends and Customers,

The VGMPlayer could play IMF Music files.

I'm working to support IMF music files on the VGMPlayer.

It's almost done and playing IMF songs now.

Please download the VGM Player again and You can have an updated version.
(You can find the location my email, I sent the information when you purchase the card)

What is IMF file and useful tools...

https://k1n9duk3.shikadi.net/imftools.html

SD Music Deluxe card has an OPL3 sound chip and the IMF files are also possible to play on APPLE II.

Hence, I researched the IMF file type and could make it run on SD Music Deluxe.

I searched for some good file formats that could work on APPLE II without any heavy CPU load.

In my thought the Music playing in APPLE II wouldn't be a problem but, when I apply the VGM songs in APPLE II,

It won't fit for games on APPLE II. so other file types are needed.

I can make my own format but, it isn't a good idea cause I can't make good songs...

So need another format it could be made by some of the composers and if possible to convert to a specified music format, it would be a nice.

I considered it an easy one and I found DRO and IMF files. Some of the files are based on MIDI format and have instrument data in to and need more consideration for APPLE II.

DRO vs IMF...

DRO file can extract DOSBOX program and good for OPL2/OPL3 

IMF file can extract some DOS games and only for OPL2(OPL3 can)

And IMF file was simper to DRO and I did for it.

VGM Player would be a good player for VGM and IMF music files.

Background MUSIC(Sound) player on APPLE II

There are Mockingboard programs that can play in the background.

I also considering making a similar program that plays IMF sound files.

it would be helpful for the user's program.

Users could insert their own sound effects while background music playing.

Hope to complete it soon.

Thanks

Ian Kim

** VGM Player updated to V1.24

In this version, It supports large IMF files and has no file size limitation.

And hidden reading applied so you can play IMF songs seamlessly.

Enjoy more OPL2 music on SD Music Deluxe card.

Thank you

Dear friends and customers,

Firmware for SD DISK][ Plus has been newly updated.

Now, Also working well on the Lemmings game program.

In this version, internal improvements have been made to better support the DISK COPY program.
Below marked OK DISK COPY programs work well.

The above programs are disk-related utilities that are mainly used.

You can easily make a NIB file created after copying it, to archive or distribute it on the Internet.

However, the negative symptom was found

Some NIB images read very slowly.

it comes due to different virtual DISK spinning.

In this case,

Use a DISK Copy Program(such as 'COPY ][ PLUS 5.1' ) and copy the DISK to self. 
In other words, Overwrite the Image by copy to DISK B --> DISK B 

How to update firmware!
Put the this SDBIOS.ROM file in the root of the SD memory,
Then proceed with the firmware update on boot menu.

Thanks

My friend found a nice WIFI SD Module as above.

With this Device, User can access SD memory card data on a WIFI Drive connection as the below.

So Copy, Move, Modify and create folders are all easy to manage files on SD memory card.

I think that it is the easiest way to access the SD memory chip via WIFI.

To configure the card, you need to refer here.

Dear friends and customers,

I am glad to announce another multi-functioning accelerator for APPLE II.

It could provide a good capability on APPLE II system with faster BASIC speed, better memory and DHGR acceleration.

I spent some months to design and testing it and now want to receive orders from international buyers.

In fact, some month ago I already completed design and sold it several cards for local friends.

but, It took long time for international customers.
I don't have much good eyes now and then every month feel a little different and this card has very small parts and hard to make by hand. New card developing is hard for me.

Spending time and ideas on the new card.. is not just developing... it is exploring the APPLE II system.

When I built new devices, i really wanted to make them different than presents others.
I want to assign unique characteristics for my card and then there could be some special functions with it.
When I considered new features into my products, it doesn't complete easy, always brings other technical issues.
Maybe I still don't understand some of WOZ machine properly....

I don't know how long could I design and make cards for friends....

I had rest some weeks and feel much better now..   so you can give me order to make yours now.

The A2 OverDrive has several funny functions.
One is Digital output.. and we can play WAV songs with it (Of cause,  It need a DA converter) 

High speed acceleration doesn't give other than the speed...
But, It bring the possibility for your APPLE II.
Faster running software will make other possibility for a real-time-based games.. 
On the graphics, it could provide smoother faster more object can move at one time period.
But, all software functions... not hard ware additions.. at least still now the accelerator card was as this.

For A2 OverDrive have hardware special functions.

1) interrupt generator
It provide IRQ or NMI interval timer interrupt. user can define the timing of interrupt. 
Hope to be used for multi processing and for event processing.

2)Slot memory
Sold memory area $C100-C7FF which are reserved for ROM on SLOT peripherals.
A2 Overdrive has ability to override this area to own RAM location.
Hence the area can use for User's area ROM or RAM.
Also $C800-CFF0 area also can override it to own RAM.
It is one of my philosophy that if technically possible then try to make new&fun functions.

3) Digital I/O
Many of people wouldn't use it except sound module function to play the WAV (sampling) sound.
I provide it for H/W fun.
8bits Input and 16bit output.

Other small functions such as fixed interval reader, R/W memory speed adjust etc...
Some are provided setup value due to limitation on APPLE II to co-operate it but, others are for special functions those couldn't find other accelerators.

I'm making the English manual for this card and some are completed but, when you order and receive the card, you can have proper manual.

Other information are scattered on this site. just consider it as an  hide and seek game.

Please order this card for an engineer who want to make more fun devices for APPLE II.

Dear customers and Friends,

SD MIDI II+ Player did update for more functions and accurate play.

In this version, It used a Hidden reading method when it need more data from Disk and results having seamless polaying.

And user can select own Level meter char. by pressing 'B' and 'N' on APPLE II.

Playing tempo tuned more accurate.

Just have a time to watch how it's playing as under.

https://youtu.be/3qIji9rbLL0

Thanks a lot

Ian Kim.

Dear Friends and Customers,

This version optimized some more for the Level meter and added on left as a channel indicator(?).

And level meter speed was incresed and good now.

It is the best what I can do with 1Mhz 6502 APPLE II.

Just watch the video.

Thanks a lot.

What is the SD MIDI ][+ ?

https://quick09.tistory.com/1347

It isn't a freeware, I will provide for SD MIDI ][+ buyers for free.

It would be announced when It finished.

Thanks a lot;

Ian Kim

Dear Friends and customers,

It's up to what I've been working on recently.
The biggest change in this version is the player used as far as the hardware supports it.
It support a progressive bar (level meta).
It is very tight to support this in the 1Mhz APPLE II.
It was made using even the hardware timer and interrupt supported by the SD MIDI II card.
It is quite difficult to support it.
After a lot of trial and error, I finally decided to use a timer interrupt for simultaneous processing.

For reference, these progressive bars are the 16 channels of MIDI, from 0 to 15 from the top.
It seems that it is too difficult to handle this with interrupts in Apple2.
It's so hard that I don't want to bother you anymore.

It works fine with or without an accelerator card but, If you use an accelerator card, the CPU load is reduced, so the tempo of the sound can come out a little more naturally. This is because the load on the interrupt side is large.

Since you have to use PRODOS, you can't completely push the IRQ routine away, so this is the best what I can do.
If I increase the speed of the progressive bar quickly, the CPU load increases, so this is the last choice.

it is a thankful result with APPLE II.

Now I have waht I wanted.

Please enjoy listening.

** Some more information **

- MIDI file format 0 is supported. Other formats can be played smoothly by converting them to MIDI 0.
- There is no MIDI file size limit. However, if the file is large, a slight delay may occur. This is sometimes canceled by the internal timer when a delay occurs, but in some cases, it cannot be canceled and may exist as a sound delay.

It isn't a freeware sorry bout it but, I will provide SD MIDI][+ customers for free.

Thank you
