Raw SRAM 64 KiB to mGBA RTC Converter

01 / Tool workbench

Use the runtime only when it is actually ready.

The application shell fails closed. An input interface is not enabled merely because a WordPress Tool record exists; the declared engine must be registered in the current build.

Raw SRAM 64 KiB to mGBA RTC Converter

BROWSER LOCAL

Checking whether the declared runtime module is loaded. No input has been processed.

Session change summary

No output has been built in this session.

What this Tool does

Append an existing same-type 16-byte mGBA RTC trailer to an explicitly selected raw SRAM 64 KiB save, using a validated template and preserving the raw source exactly.

Verification boundary

Raw source must be exactly the selected SRAM 64 KiB size. A separate same-type mGBA template must already contain the 16-byte RTC trailer. No RTC state is synthesized. Save-memory type is an explicit user assertion. Phase 72 does not auto-detect GBA cartridge save type, synthesize or alter RTC state, repair game checksums, or treat extension/size as game identity.

Output and rollback

mGBA save containing the exact raw source plus the template RTC trailer, raw-source rollback, and deterministic SHA-256-bound proof JSON. The original selected source is never modified in place.

Before you convert

Keep an independent backup, use the exact representation named by this Tool, and test the resulting copy in the intended emulator or utility before replacing any working save.

02 / Compatibility

Know the supported input before opening a file.

Compatibility fields are intentionally explicit. Missing values stay unclaimed rather than being filled with generic assumptions.

Accepted extensions

.srm.sav

Platforms

Game Boy Advance

Supported versions / editions

Raw battery-save bytes to mGBA standalone representation using only a byte-identical RTC record copied from the user-selected same-type template.

Input constraints

Raw source must be exactly the selected SRAM 64 KiB size. A separate same-type mGBA template must already contain the 16-byte RTC trailer. No RTC state is synthesized.

Known limitations

Save-memory type is an explicit user assertion. Phase 72 does not auto-detect GBA cartridge save type, synthesize or alter RTC state, repair game checksums, or treat extension/size as game identity.

Output / result

mGBA save containing the exact raw source plus the template RTC trailer, raw-source rollback, and deterministic SHA-256-bound proof JSON.

03 / Instructions

Use a reversible workflow.

File-oriented workflows start with an untouched original. Tool-specific instructions add only details documented for this utility.

01Keep the original
Preserve an untouched copy before creating or transforming binary output.
02Confirm scope
Match the file size, format, platform, and version to the support information on this page.
03Process locally
Use the runtime only when the page reports that its declared engine is loaded.
04Validate output
Compare or test the result before replacing any working source file.

Tool-specific steps

Choose the raw source and a same-type mGBA template that already contains an RTC trailer. SaveEditor copies only the 16 RTC bytes from that template, reopens the target and proves the raw source round-trips unchanged.

04 / Privacy and processing

The processing mode is part of the product contract.

SaveEditor.com should state local processing only when the implementation truly keeps file contents in the browser. Server or hybrid processing must be disclosed just as clearly.

Declared mode

Browser local

Runtime state

Operational

Tool-specific privacy notes

All Phase 72 operations run only on explicitly selected local files in the browser under the permanent 16 MiB per-file ceiling. No fetch, XMLHttpRequest, WebSocket, sendBeacon, account login, cloud synchronization or remote conversion service is used.

05 / Troubleshooting

When a file is rejected, do not force it.

A rejection can indicate an unsupported size, format, version, platform, or byte sequence. Preserve the original and correct the input instead of bypassing validation.

Wrong file or size

Re-check the documented input type and browser size limit before retrying.

Unsupported format

A generic converter does not imply support for every game-specific container, signing scheme, or serialization format.

Source was modified

Return to the untouched source instead of repeatedly processing a damaged or partially transformed file.

Known Tool issues

A refusal means the existing verified parser/layout/writer or a Phase 72 round-trip predicate failed. Renaming an extension, matching a size, or supplying a template cannot bypass strict source/target checks.

06 / Verification

Support claims should be traceable.

The verification date, method notes, and public references are kept separate from marketing language so compatibility can be reviewed over time.

Method notes

Verified as a narrow surface over existing conversion authority with deterministic SHA-256 evidence, source immutability, strict target reopen or exact-slice proof, byte-identical rollback where applicable, malformed-input refusal, independent reference vectors and source/installable parity.

07 / FAQ

Questions to answer before editing.

These answers are generated from the Tool record and current runtime state rather than generic compatibility promises.

Is Raw SRAM 64 KiB to mGBA RTC Converter ready to use?

The Tool record is verified and declares an operational runtime. The page enables its input controls only when the declared engine module is loaded in the current build.

Does processing stay in the browser?

Yes for this declared mode. The loaded runtime processes the explicit input in the browser; Tool-specific privacy notes describe the exact scope and limits.

Should I keep the original file?

Yes. Keep an untouched source file until any generated output has been validated.

What if my input is rejected?

Use the validation message to correct the base, encoding, width, timezone, byte alignment, or size. The runtime does not guess through invalid input.
