MagicBIN 2
Build your EPROMs

Load the files .bin, .rom, .hex, arrange them in any order you like and instantly see where they end up And how much space they take in the EPROM. You check the contents with the hex editor and the character ROM viewer, then create the file to burn with the programmer: even split even/odd for two EPROMs in parallel.

WHAT IT DOES

Everything you need
to burn an EPROM

All EPROMs

From the 2708 to the 27C080, 28C EEPROMs and 39SF Flash. The 27C400/800/160/320 are marked as usable in 8 or 16-bit mode; 16-bit EPROMs warn you that don't work on 8-bit systems.

Drag and reorder

Drag the files into the window and reorder them by dragging the rows. Reads .bin, .rom, .img, Intel .hex, Motorola .s19 and C64 cartridges .crt.

Graphical map

See at a glance where each file sits, the free space, overlaps and what overflows the EPROM. With slot see multi-ROMs with a switch (e.g. 4 C64 Kernals).

Precise addresses

Fixed address, 1K…1M alignment, empty blocks of a given size or “up to address”, e Repeat to fill the EPROM with copies of the same ROM.

FF / 00 fill

Unused space is filled with FF (blank EPROM), 00 or a value of your choice, even a different one for each empty block.

Hex editor

Edit bytes, search for sequences or text, choose ASCII, PETSCII, ZX or ATASCII. It tells you which file and which chip each byte ends up.

Character and graphics ROMs

View and redraw the fonts of the C64/VIC-20/C128, ZX Spectrum, ZX81, Atari 8-bit and ST, Amstrad CPC, MSX, BBC, PC, Apple II, NES tiles and Game Boy. With “Find font” finds them on its own.

Even / odd and multi-chip

Split the ROM for 2 HI/LO EPROMs, 4 EPROMs (Atari TT), 2 16-bit EPROMs (Amiga), sequential banks, or the the 6 chips of TOS 1.04. With byte swapping for programmers.

TOS CRC fix and Kickstart

Recalculate the TOS 2.06 CRC after a patch (without a working Atari) and the checksum of the Amiga Kickstart. It also merges dumps of separate EPROMs.

Ready-made configurations

One click for Atari ST/STE/TT, Amiga 500 and 1200, C64 multi-Kernal on 27C256/27C512, ZX Spectrum multi-ROM.

Projects that don't get lost

The project .mbproj also saves the file data: you can reopen it even if the originals have since been moved or deleted.

Undo, CRC, checksum

Unlimited undo/redo, CRC32 and byte sum (like the TL866/T48 programmers) for every file and every EPROM to be burned.

QUICK GUIDE

From ROM to EPROM
in 6 steps

Choose the EPROM

In the left-hand column choose the chip (e.g. 27C256). If you use several chips together, choose the organisation: 2 even/odd EPROMs (HI/LO), 4 byte-wide EPROMs, sequential banks… The total capacity updates automatically.

Add the files

Drag them into the window or use Add files (Ctrl+THE). They are placed one after another: reorder them by dragging the rows or with the arrows (Alt+↑/↓).

Arrange the addresses

Select a file and in its properties choose Fixed address or Align to. To leave a gap use Empty block, also “up to address” 4000. Addresses are entered in hexadecimal. For multi-ROMs, enable the slot (es. 8 KB).

Check the contents

Double-clicking a file (or the map) opens the HEX editor. In the Graphics / Characters tab choose the format (C64, Spectrum, Atari…) or press Find font.

Fill and checks

Choose FF or 00 for the free space. Red rows go beyond the EPROM, orange ones overlap. If you have patched a TOS 2.06, use Tools → Fix CRC.

Create the ROM and save the project

Press Build ROM (Ctrl+And): you see the list of files that will be created and save them to a folder. Save the project with Ctrl+S.: the data is stored inside it too.
